NextGen Fiber: 10 Gbps XGS-PON Heads to Frontier, Greenlight Networks

As gigabit internet becomes more common across the United States, some ISPs are seeking a speed advantage by offering even faster speeds to residential and business customers. On Tuesday, Nokia announced Frontier Communications and Rochester, N.Y.-based Greenlight Networks would be upgrading their fiber networks to the company’s XGS-PON solution, which can handle 10 Gbps upload and download speeds.

“Next Generation PON technologies such as XGS-PON are increasingly being deployed as demand for ultra-broadband applications and services continue to grow,” said Julie Kunstler, principal analyst at Ovum, in a statement. “Providing operators with the ability to use the same passive and active plants, XGS-PON solutions like Nokia’s can be quickly deployed and used to capture 10Gbps service opportunities that help operators to improve the return on their existing fiber network investments.”

Many existing fiber networks currently rely on GPON (gigabit passive optical network) technology — which allows one fiber in a bundle of fibers to service multiple homes and businesses. GPON networks are typically capable of download speeds of 2.488 Gbps and shared upstream speeds of 1.244 Gbps. Many ISPs using GPON technology typically offer fast download speeds, but often slower upload speeds.

Next generation XGS-PON allows up to 10 Gbps in both directions over existing fiber networks. In fact, the technology is future proof, allowing operators to immediately upgrade to faster speeds and later move towards Full TWDM-PON, an even more robust technology, without expensive network upgrades.

Most providers are leveraging XGS-PON technology to deliver symmetrical broadband — same upload and download speeds — to residential customers and to expand network capacity to avoid congestion. XPS-PON technology also supports faster-than-gigabit speeds than can be attractive to commercial customers.

Frontier intends to deploy Nokia’s technology in ex-Verizon markets in California, Texas, and Florida, beginning in Dallas-Fort Worth. It will allow Frontier to beef up its FiOS network and market stronger broadband products to Texas businesses. In Rochester, Greenlight will use the technology to upgrade its fiber service, which competes locally with Frontier DSL and Charter/Spectrum. Spectrum recently introduced gigabit download speed in Rochester. Greenlight can now expand beyond its 1 Gbps offering, but more importantly, increase its maximum upload speed beyond 100 Mbps.

“Greenlight is constantly looking at ways we can deliver new services that fit every customer need. We pride ourselves on offering the fastest internet speeds available in the markets we serve and Nokia’s XGS-PON technology will play a critical part in our ability to deliver these services to our customers,” said Greenlight CEO Mark Murphy. “With Nokia’s next-generation PON fiber solution we will be able to deliver the latest technologies, applications, products and services quickly and reliably to our customers and ensure they have access to the ultra-broadband speeds and capacity they require now and in the future.”

Nokia points out its XGS-PON technology may also be very attractive to wireless companies considering deploying 5G services. Extensive fiber assets available in area neighborhoods will be crucial for the success of millimeter wave 5G technology, which relies on small cells placed around neighborhoods and fed by fiber optics.

Control Freak: Frontier Goes All Out to Limit Minnesota Investigation

Phillip Dampier June 5, 2018 Broadband Speed, Competition, Consumer News, Frontier, Public Policy & Gov't, Rural Broadband Comments Off on Control Freak: Frontier Goes All Out to Limit Minnesota Investigation

Frontier Communications spent more time working on ways to keep Minnesota customers from turning up at upcoming public hearings to discuss their poor service than actually resolving those customers’ service troubles.

Minnesota has a big problem with Frontier. The company has been the subject of an unprecedented number of customer complaints and negative comments — 439 in just a five-week period from Feb. 12 – March 19, 2018 about poor service, repair crews that don’t show up, woefully inadequate internet service, poor billing and customer service practices, and false advertising. As a result, the Minnesota Public Utilities Commission (PUC) launched an investigation into Frontier’s service performance in the state (Note: most links in this article will require a free account at the Minnesota Department of Commerce to read. Register here.), which is about the same time Frontier’s top executives in the state began a campaign of damage control focused primarily on keeping internet complaints out of the public record.

The complaints, summarized below by the Minnesota PUC, are familiar to many Frontier Communications customers around the country:

Some parties allege being without telephone service for about a week’s time on multiple occasions. Such instances resulted in customers being unable to access 911 or connect medical devices dependent on land telephone lines. Missed incoming calls, noise on phone lines and other phone quality complaints are not infrequent. Nearly all comments mention that they are being charged for service product(s) not being provided as promised, often with related billing and cancellation disputes as a consequence.

Nearly all parties complain that Frontier’s customer service representatives provide inconsistent information on available service in the customer’s area and its price. Many report routinely being sold higher level (more costly) service or hardware as a remedy for service problems that remain or return after the recommended solution is in place. Customers often note being told later that the upgraded service they were sold is not available at their location.

Many complaints concern home service visits that require subsequent visits to correct or augment earlier actions, often with charges but no resulting remedy. Often customers say they experience long delays in getting repairs scheduled, must take lengthy time from work to await for service representatives to arrive only to find problems cannot be remedied. Missed service appointments, mistaken disconnections, unrequested service additions, installation and wiring errors are common complaints.

Customers frequently report discovering they are allegedly on a contract with penalties for ending service early even if they had explicitly refused to accept long term contracts. Apparently such contracts automatically renew without customer notice upon payment of the first month of the new period. Customers indicate being warned of damaging credit reports in addition to accumulating penalties if they do not pay disputed bills. Billing disputes also include promised discounts not being provided, penalties accumulating on disputed amounts, and checks being sent but not being credited to accounts.

Based on decades of experience, the PUC staff knew trouble when they saw it, and found the complaints about Frontier credible and serious.

“The total number of comments and complaints, often with detailed documentation, appears to indicate that widespread problems with service quality, customer service and billing exist,” PUC staffers wrote. “Customers express the very highest levels of frustration over service quality and over their interactions with Frontier representatives. Customers express despair over their billing and lack of alternatives. Finally, they express outright ‘gratitude for the hope that someone might come to their aid.”

Customers hoping for rescue discovered Frontier’s legal team instead, on a mission to do everything possible to limit the scope of the state’s investigation and discourage public participation by suggesting customers with internet complaints would not be welcome at the hearings.

Frontier, joined by fellow independent phone company CenturyLink, immediately realized the implications of holding public hearings about the performance of their DSL service in Minnesota. Both companies likely receive an even larger number of service complaints than regulators do, and here is just a sampling:

‘If you don’t like our service in the countryside, move to town!’

Graham Adams: “We have had Frontier for a little over 2 years and have had nothing but problems. Internet is constantly out for days sometimes weeks at a time. I think it’s preposterous they can charge me $42 a month for 5 Mbps service that is inconsistent at best. Because we live outside city limits Frontier is the only internet service available.”

Christopher Krolak:  “I have been a Frontier Communications customer for about 4.5 years. I live in an area where there isn’t a lot of competition for high speed internet. I pay $30 per month for “up to 6 Mbps” service but real world speeds are best case 2 Mbps and fall to 0.3 Mbps during peak times. When I’ve called about the large discrepancy between advertised speed and actual speed, Frontier has responded that the area I live in is only provisioned for about 2 Mbps speed and an infrastructure upgrade is required. Frontier is unwilling to give any timeline forecast for when such upgrade will be made.”

Sylvia Svihel: “We have been a customer of Frontier’s for 41 years as it has been the only land line in our area. Our phone, internet and Dish service are tied into the same package. The prices keep going up. We did upgrade our service for a faster speed but we see zero improvement on the speed…just an even higher bill. I have lost track of how many times we have contacted Frontier on lost service. They usually just say it’s the modem and to reboot it and everything will be OK. I reboot the modem, sometimes multiple times a day.”

Jay Johnson: “I have been a Frontier customer for internet for a long time. The service I pay for is “up to 6 Mbps” but I’d be lucky to get 1.2 Mbps. They have a monopoly in this part of Mille Lacs County. There are really no other options other than satellite or cellular and those are not really any better speed and certainly not price.”

Roger Wikstrom: “We have had Frontier service for 32 years. Beginning about 20 years ago we added internet service, which has always been unreliable. […]We complained many times and had dozens of service calls over the years. At one point, the technician told us we were out in the country, the brass at Frontier did not really care about our service, and that if we wanted good service from Frontier, we should move to town.”

Based on a growing record of complaints, the PUC sought to hold public hearings to gather more information from consumers and to better understand the problems being experienced by Frontier customers. Almost immediately, Frontier began to claim the complaints were few and far between, and most of the complaints seen on the record pertain to the company’s DSL internet service, which Frontier claims is not subject to oversight by the PUC and cannot be a subject on the agenda of the public hearings.

Frontier’s Lawyers: It would confuse customers and give them false hope if they believed the Commission can force Frontier to improve DSL service.

Frontier’s attorneys lecture the Minnesota Department of Commerce

Frontier’s attorneys have repeatedly objected to any investigation or hearings that cover anything beyond the performance of Frontier’s landline telephone service. Frontier was joined by CenturyLink, which also argues Minnesota no longer has any jurisdiction over broadband issues, noting a state court recently ruled telecommunications services are subject to state regulation and oversight, while “information services” like internet access are not.

Frontier was particularly irritated that the hearings could stray into an open mic session filled with consumers upset about Frontier’s DSL service. Unless customers were warned in advance the public meetings were not to include discussions about internet service, it “would create false expectations and confusion for customers.” In fact, if regulators permitted this, Frontier claims it would “violate federal law.”

“Holding public hearings directed to internet access service complaints would not be constructive because the Commission would be precluded from taking action concerning internet service rates or service quality using any information it may collect during the public hearings,” Frontier added.

Here is where the Republican-dominated FCC comes to the aid of Frontier and CenturyLink. At the insistence of FCC Chairman Ajit Pai, stripping away state oversight of poorly performing telecom companies was a key industry benefit gained with the implementation of Pai’s “Restoring Internet Freedom Order,” implemented on Jan. 8, 2018. That FCC Order swept away former FCC Chairman Thomas Wheeler’s favored classification of broadband as a “telecommunications service,” which is subject to oversight, and instead put it firmly back in unregulated territory as an “information service.” That proved helpful to CenturyLink’s argument:

In making its decision the FCC broadly preempted state regulation and decided that “regulation of broadband Internet access service should be governed principally by a uniform set of federal regulations, rather than by a patchwork that includes separate state and local requirements.” The FCC expressly preempted any ‘public utility-type’ regulations, . . . akin to those found in Title II of the Act and its implementing rules . . .”

Frontier’s lawyers made so much noise about the prospect of internet complaints being heard at public hearings, the Commission elected to allow Frontier to draft the public hearing notices that would be inserted into customer bills and published in newspapers around the state. The Commission also allowed Frontier to clarify the limits of the Commission’s jurisdiction over internet service — a decision it would soon regret.

Minnesota is unusual because it is served by dozens of smaller, typically independent telephone companies, which include Frontier and its subsidiary Citizens Telecommunications of Minnesota.

Give Frontier an inch, and they take a mile, according to some company critics who told Stop the Cap! were astonished on April 30th when Frontier shared its draft notice with the public. The Minnesota attorney general’s office politely characterized Frontier’s notice as a “very narrow reading of the Commission’s jurisdiction over internet service.”

Here it is, as originally proposed by Frontier in April:

The jurisdiction of the MPUC includes telephone services, but does not include Internet services or the speed or quality of access or connections to the Internet or the communications services, such as Voice Over IP, that are provided using only the Internet.

The attorney general’s office objected to Frontier’s characterization of VoIP phone service as completely unregulated. A subsequent proposed revision by Frontier was not welcomed by the attorney general’s office either:

The jurisdiction of the MPUC includes telephone services, but does not include Internet access services or the rates, speed, quality, or availability of Internet services.

After motions to reconsider, the Commission ultimately reversed its earlier decision allowing Frontier to write its own text:

While the Commission does not want to mislead the public into believing the Commission has jurisdiction over matters that are solely within the province of federal entities, neither does the Commission want to erroneously disavow any aspect of the jurisdiction it does have over the goods and services that Frontier provides to its Minnesota customers.

Given the tension between these two objectives—and the fact that this dispute is arising in the context of drafting the language of a public notice—the Commission will resolve this matter by simply eliminating the requirement that the notice address the topic of the Commission’s jurisdiction over aspects of internet services.

Frontier DSL in Watertown: “47 minutes to upload one small photo to Facebook.”

While Frontier argues about jurisdiction issues, customers like Dr. Kathleen McCann — a dentist serving rural Watertown Township in Carver County, share their stories about how inadequate internet access directly harms local communities, and in her case, her patients.

Dr. McCann

“Frontier Communications is my only option for internet,” McCann told regulators. “My internet service is worse than dial-up. I am charged for ‘DSL High Speed Broadband’ on my monthly bill, but my download speeds are only averaging 2 Mbps and the upload speeds average 0.28 Mbps. As a dentist, I am not able to email dental X-rays. It took me 47 minutes to upload one small photo to Facebook recently.”

McCann added what is even worse than her DSL speed is Frontier’s service. She claims there are “frequent drops” every day, and a technician from Frontier measured an average of 20 small service outages a day. One day her service dropped 400 times. Outages can last days.

“The most recent Frontier internet outage began March 3 and as of March 7, there are at least 27 homes in my neighborhood still without internet service,” McCann added. “This is unacceptable, especially since many of these 27 Frontier customers are running their businesses entirely from home. Calls to Frontier, when finally answered after sometimes 40 minutes on hold, are ineffective.”

Public meetings to discuss Frontier service are scheduled in these areas of Minnesota (exact locations to be determined):

  • Ely: September 4, 2018, at 6:00 p.m.
  • McGregor: September 5, 2018, at 6:00 p.m.
  • Wyoming: September 12, 2018, at 6:00 p.m.
  • Slayton: September 25, 2018, at 6:00 p.m.
  • Lakeville: September 26, 2018, at 2:00 p.m. and 6:00 p.m.

AT&T’s Curious Decision to Abandon Data Throttling Appeal to Supreme Court

Phillip Dampier June 4, 2018 AT&T, Broadband Speed, Data Caps, Editorial & Site News, Net Neutrality, Public Policy & Gov't Comments Off on AT&T’s Curious Decision to Abandon Data Throttling Appeal to Supreme Court

Last week, AT&T announced its intention to abandon an appeal of a decision of the 9th Circuit Court of Appeals granting the Federal Trade Commission the right to continue its lawsuit against AT&T for speed throttling its “unlimited data” wireless customers.

The notification came in a surprising four sentence notice filed with the court May 30:

At the May 10, 2018 case management conference in this matter, AT&T informed the Court that it expected at that time to request a 60-day extension from the Supreme Court of the deadline to file a petition for certiorari. See Audio Recording of May 10, 2018 Hr’g at 7:22. Since that hearing, AT&T has decided not to request such an extension and not to file a petition for certiorari to review the decision of the en banc Ninth Circuit, see 883 F.3d 848 (9th Cir. 2018). The deadline to file a petition for certiorari lapsed on May 29, 2018.

AT&T spokesman Mike Balmoris later told reporters: “We have decided not to seek review by the Supreme Court, to focus instead on negotiating a fair resolution of the case with the Federal Trade Commission.”

AT&T’s sudden change of heart surprised many observers, including some closely following the case at the 9th Circuit, which has held regular court supervised meetings to prepare for the widely expected Supreme Court challenge. AT&T notified the court in early May it would file its appeal as soon as May 29, and the court was preparing new discovery guidelines and deadlines between the two parties as the case proceeded.

AT&T had achieved a major victory in 2017 when a three-judge panel at the Ninth Circuit agreed with AT&T’s argument that the FTC had no jurisdiction over the company because part of its business includes traditional telephone service, something defined in law as being regulated exclusively by the FCC. At the same time, the FCC did not seem to have jurisdiction either, because wireless data throttling took place over a network not subject to common carrier service regulations.

Ninth Circuit Court of Appeals — San Francisco.

The Ninth Circuit then agreed to hear the case once again, this time “en banc” — meaning the full court would re-hear the case instead of a limited panel of three judges. In February, the court unanimously found the FTC did have regulatory jurisdiction over AT&T after all:

We conclude that the exemption in Section 5 of the FTC Act – “except . . . common carriers subject to the Acts to regulate commerce” – bars the FTC from regulating “common carriers” only to the extent that they engage in common-carriage activity. By extension, this interpretation means that the FTC may regulate common carriers’ non-common-carriage activities.

[…] This statutory interpretation also accords with common sense. The FTC is the leading federal consumer protection agency and, for many decades, has been the chief federal agency on privacy policy and enforcement. Permitting the FTC to oversee unfair and deceptive non-common-carriage practices of telecommunications companies has practical ramifications. New technologies have spawned new regulatory challenges. A phone company is no longer just a phone company. The transformation of information services and the ubiquity of digital technology mean that telecommunications operators have expanded into website operation, video distribution, news and entertainment production, interactive entertainment services and devices, home security and more. Reaffirming FTC jurisdiction over activities that fall outside of common-carrier services avoids regulatory gaps and provides consistency and predictability in regulatory enforcement.

In short, AT&T’s “get out of regulatory oversight free”-card was revoked, much to its consternation. The company promised a fast appeal to the Supreme Court. The case concerned a number of observers, not the least of which was the Federal Communications Commission, which has been so concerned about AT&T’s novel argument to escape regulation, it filed a brief supporting the FTC with the court:

If the en banc Court were to adopt AT&T’s position that the FTC Act’s common-carrier exception is “status-based” rather than “activity-based,” contrary to the reasoned analysis of the district court below, the fact that AT&T provides traditional common-carrier voice telephone service could potentially immunize the company from any FTC oversight of its noncommon-carrier offerings, even when the FCC lacks authority over those offerings—creating a potentially substantial regulatory gap where neither the FTC nor the FCC has regulatory authority.

That approach is contrary to a common-sense reading of the relevant statutes and could weaken or eliminate important consumer protections. While AT&T may prefer to offer services in a regulatory no man’s land, the law does not dance to AT&T’s whims.

While AT&T publicly expressed confidence about its appeal right up to the day it abandoned it, minutes from the Ninth Circuit trial scheduling and progress conferences reveal AT&T and the FTC were already privately talking with each other to avoid further litigation:

“Parties reported that they are conducting settlement negotiations.”

All observers agree a successful appeal by AT&T to the Supreme Court could have put telecommunications laws and regulations into chaos. Had AT&T successfully restored the three-judge panel’s decision, any telecommunications company could walk away with impunity from FCC and FTC oversight by simply starting a small telephone company serving just a handful of customers. Just one product or service subject to common carrier rules could effectively immunize a phone or cable company from regulations indefinitely, or until Congress changed the law to close that loophole.

Some observers predict AT&T’s decision not to appeal is a prelude to an imminent, favorable permanent settlement of the four-year old case. The evidence strongly suggests AT&T will likely escape any significant monetary punishment, and affected consumers may not get significant (if any) compensation for AT&T’s prior acts:

  • The FCC shows no sign of following through on a 2015 press release threatening AT&T with $100 million in fines for its failure to properly disclose its speed throttling policy arbitrarily imposed on unlimited data customers who exceeded a company-defined amount of data usage. At the time the press release was issued, there were three Democrats and two Republicans serving on the Commission. Both of those Republicans opposed the fine and are now part of the Republican majority at the FCC under the Trump Administration. The FCC admitted in court papers that no further action has been taken to fine AT&T. The case was largely left in the hands of the FTC.
  • During the Obama Administration, the FTC claimed it was interested in pursuing refunds for affected customers and punishing AT&T for its throttling practices. Last week, Andrew Smith, the FTC’s new director of the Consumer Protection Bureau told an audience today’s priority it to monitor providers over traffic throttling and making sure those practices are transparently disclosed to customers. “We’re planning to examine current practices in the industry,” Smith said. “We’re looking for areas in which ISPs may be engaged in unfair or deceptive practices, and we will bring enforcement action as appropriate.”

Smith

For AT&T, the decision to drop its appeal may have come down to whether it preferred to temporarily escape regulatory oversight until an enraged Congress passed new laws to put AT&T and other telecom companies back under oversight, or living with the kind of “light-to-little touch” regulatory approach favored by the Trump Administration and its regulatory agencies. Whatever deal emerges between AT&T and the Trump Administration’s FTC will likely be “win-win” for the company and the regulator, with consumers offered only token relief.

The goals likely to be achieved in any settlement:

  • AT&T would clearly like to avoid a $100 million fine and other enforcement actions, so agreeing to ease throttling (something it has done already) and better disclose the practice would hardly create a problem for the company, especially if fines are dropped as a result.
  • The FCC’s new “net neutrality” policy depends almost entirely on effectively abdicating oversight responsibility to the FTC, something embarrassing and hard to justify if AT&T managed to permanently bar the agency from regulating the company.
  • The FTC can claim victory by telling consumers they are watching ISPs for undisclosed and unwarranted throttling, without opening up new legal challenges by outright banning of the practice, heavily fining violators, or collecting damages on behalf of customers victimized by prior bad acts.

AT&T Reiterates 5G Fixed Wireless is a Waste of Resources: Pushes Fiber to Home Instead

AT&T does not see fixed wireless millimeter wave broadband in your future if you live in or around a major city.

John Stephens, AT&T’s chief financial officer, today reiterated to shareholders that building a small cell network for urban and suburban fixed wireless service does not make much sense from a business perspective.

“It’s the cost efficiency,” Stephens told an audience at Cowen and Company’s 46th Annual Technology, Media & Telecom Broker Conference. “Once you [get] the fixed wireless connection from the alley to your house, that’s great you can do that, but you have to get it from the alley into the core network.”

Stephens

Stephens noted that once AT&T realized it would require a collection of small cells to hand wireless traffic off, “building that out can be very expensive when you’re likely doing it in an urban market in a residential area that already has a lot of fiber [or] a lot of competition [from] incumbent telephone and cable companies.”

AT&T sees a likely different future for fixed wireless based on in its ongoing trials underway in Austin, Tex. — selling the service to commercial and manufacturing customers with robotic equipment and other machinery that need instant and fast wireless communications to communicate with each other and back to a central point.

Stephens believes a better idea for its 30 million U-verse fiber-near-the-home customers is to extend fiber directly to those customers’ homes. Stephens said AT&T would be financially better off scrapping the remaining copper wire running the last 500 feet from a customer’s home or business to the nearest fiber-equipped pedestal and give customers dedicated fiber to the home service instead.

“It may be very inexpensive for us compared to the [5G] alternative and gives the customer a tremendous level of service,” Stephens added.

Where millimeter wave could make sense is in exurban and rural areas where clusters of homes could potentially be reached by fixed wireless, assuming there was fiber infrastructure close enough to connect those small cells to AT&T’s network. But AT&T seems to be more interested in applying the technology in commercial and Internet of Things (IoT) applications where wireless access can be essential, and would be much easier to deploy.

Verizon, in contrast, is expanding millimeter wave fixed wireless broadband trials, with the hope of selling a wireless home internet replacement.

Cable Broadband in 2025: DOCSIS 4.0 Could Raise Speeds as High as 60/60 Gbps

Phillip Dampier May 24, 2018 Broadband Speed, Consumer News 6 Comments

The next standard for cable broadband is due around 2025.

Just as the cable industry is widely introducing gigabit download speed supported by DOCSIS 3.1 technology, cable engineers are working on a way to boost upload and download speeds to as high as 60 Gbps (60,000 Mbps) starting as soon as 2025.

According to a new article in Light Reading, DOCSIS 4.0 (or DOCSIS.Next) represents a transformational leap of cable broadband technology. Jeff Finklestein, Cox Communications’ executive director of advanced technology, claims the next major broadband update will be able to use at least 3 GHz of RF spectrum available on existing coaxial cable for high-speed internet. That is more than twice the 1.2 GHz that being used by some cable systems for today’s DOCSIS 3.1 (and the 1.8 GHz that will be needed to support DOCSIS 3.1 FD, which will allow operators to dramatically boost upload speeds by 2020.)

Designed for the next decade, DOCSIS 4.0 will support 30/30 Gbps speed (or 60/60 Gbps if an operator is willing to dedicate up to 6 GHz for broadband). Today’s coaxial cable networks can use up to 10 GHz of RF spectrum in all, with some compromises and allowances to deal with possible signal ingress and other types of interference.

By the time DOCSIS 4.0 arrives, many cable operators will not mind delivering the majority of their available spectrum to broadband, because most are expected to eventually deliver a single broadband stream that collectively supports IPTV, digital phone, and broadband service.

Finklestein

To make the next generation of cable broadband possible, cable systems will likely need to reduce the amount of copper coaxial cable in their networks and push fiber optics deeper into neighborhoods. The more optical fiber the better — the technology is not hampered by coaxial cable’s limitations and degradation.

Engineers are also likely to shift away from DOCSIS 3.1’s orthogonal frequency division multiplexing (OFDM) modulation and use advanced wave form technology instead.

While engineers are excited about the project, some suspect DOCSIS 4.0 may be a tougher sell for cable industry executives, asked to invest in another transformational broadband upgrade less than ten years after DOCSIS 3.1 was introduced. Many cable operators using older cable network plants will have to spend millions on overhauls and upgrades, and there is some question about whether that kind of additional investment in a Hybrid Fiber Coax (HFC) network platform makes sense. Altice certainly does not believe so, and in 2016 elected to scrap Cablevision/Optimum’s HFC network and replace it with fiber to the home service.

As cable companies push fiber deeper into their networks, the cost of taking fiber the rest of the way to customer homes and businesses is coming down as well.

The cable industry has generally dismissed fiber to the home service as an extravagant and expensive technology to deploy, arguing cable’s HFC networks can deliver the broadband speeds that are commercially in demand today, while working on upgrades like DOCSIS 4.0 to meet consumer and business demands tomorrow, without the cost of tearing up streets to lay optical fiber.
