Fears that growing global Internet traffic might someday result in an Internet brownout were made irrelevant this week after Britain’s BT and Alcatel-Lucent achieved a new speed record in a field trial of ‘flexible grid’ infrastructure that reached 1.4 Terabits per second over an existing fiber network.

Flexgrid technology increases the density of individual transmission channels on traditional fiber networks, resulting in 42.5 percent better transmission efficiency over current standards.

“BT and Alcatel-Lucent are making more from what they’ve got,” explained Oliver Johnson, chief executive of broadband analyst firm Point Topic. “It allows them to increase their capacity without having to spend much more money.”

The trial was conducted through the overlaying of an “Alien Super Channel” comprised of seven 200 Gigabits per second (Gb/s) channels bundled together to provide a combined capacity of 1.4Tb/s. By reducing the spectral spacing between the channels from 50GHz to 35GHz using the 400Gb/s Photonic Services Engine (PSE) technology on the 1830 Photonic Service Switch (PSS), spectral efficiency is enhanced by almost 43%. The 1830 PSS can be used as an optical extension shelf of the 7750 Service Router (SR) and the 7950 Extensible Routing System (XRS). Flexgrid is the key to creating high-capacity, spectrally efficient super channels. The super channel is “alien” because it operates transparently on top of BT’s existing optical network.

The speeds were achieved on a standard 410km fiber link between BT’s Adastral Park research campus in Ipswich and the BT Tower in London.

The new transmission technology means existing fiber infrastructure can easily manage far faster speeds and more bandwidth without costly upgrades and more fiber installation.

While the new technology is unlikely to be deployed to individual customer homes and businesses, it is likely to become important for Internet backbone networks which handle connectivity between Internet Service Providers.

Companies like Cisco have warned for years that existing infrastructure might be unsuitable to manage the growth of Internet traffic, resulting in a potential “exaflood” of data over a congested Internet, resulting in “brownouts” that slow or stop Internet connections. But Alcatel-Lucent and BT have demonstrated that ongoing technological advances make such problems unlikely, because as Internet traffic increases, technological improvements assure that capacity keeps up at an affordable cost.

A Wall Street research firm is asking questions about the “mixed messages” AT&T is sending consumers over its broadband offerings.

Ovum Research senior analyst Kamalini Ganguly said AT&T’s fiber to the home (FTTH) network in Austin — set to upgrade customers to 1Gbps next year — is likely to confuse AT&T and its shareholders over the future direction of AT&T’s current fiber to the neighborhood (FTTN) upgrade effort, dubbed Project VIP.

Having spent eight years deploying the U-verse FTTN service, a year ago AT&T chose to expand household coverage and upgrade speeds. That effort, called Project VIP, is still ongoing and until now has reflected AT&T’s projection that 45Mbps downstream (and 6Mbps upstream) should be good enough for the majority of its customers.

AT&T says it intends to boost part of its Project VIP footprint to 75Mbps or 100Mbps with VDSL2 vectoring, but the extent of this is unknown. It has also deployed a small amount of GPON FTTH in greenfield markets, typically designed to support 80–100Mbps to each household. Also as part of Project VIP, it plans to reach 1 million businesses with symmetric 1Gbps FTTH.

However, the GigaPower offering in Austin will be AT&T’s first 300Mbps or 1Gbps mass-market FTTH offering targeting consumers, not just businesses, in a major market. It is also a symmetric offering, meaning upstream will be 1Gbps as well. Those speeds are far higher than what Project VIP will deliver to the majority of consumers. The jump from 45/6Mbps to 1/1Gbps for consumers raises questions around its strategy. The cost issue looms large. Deploying 1Gbps point-to-point FTTH will continue to cost much more than GPON FTTH, which in turn still costs a lot more than FTTN – even with vectoring. AT&T needs to explain better what has changed from last year in the business case for FTTH over FTTN.

Wall Street is asking questions because AT&T has repeatedly denied its fiber project in Austin has anything to do with Google’s intention to offer a similar fiber network in Austin next year and everything to to do with its general broadband strategy. There is increasing skepticism about AT&T’s veracity on that point, particularly after AT&T announced pricing that was suspiciously similar to what Google charges its fiber customers in Kansas City and is likely to charge in Austin. Ovum’s researchers also took special note of AT&T’s intention to “examine its customers’ browsing habits in order to generate incremental revenues with targeted ads and commercial offers.”

There is evidence Google is proving a growing market disruptor, turning cable and telco industry pricing models upside down where the search engine giant threatens to compete. Industry plans to charge premium prices for incrementally faster broadband speed tiers is at risk with Google’s gigabit offer, priced at just $70 a month. Comcast charges up to $300 a month for considerably less speed. Community owned fiber broadband providers are increasingly adopting Google’s pricing model themselves. EPB in Chattanooga reduced the price of its 1Gbps tier from $300 to $70 earlier this year.

“By accepting a ceiling of $70, AT&T may be making it harder to break even,” writes Ganguly. “We may see lower prices cascading down for all broadband services. AT&T runs the risk of de-valuing its own broadband business and ultimately that of others too. On a more positive note, demand for 1Gbps was seen as questionable when prices were unaffordable for consumers and when multiple HD streams can be supported by 40–50Mbps. With these price levels however, demand may spike and boost the business case for 1Gbps.”

Rural Norway is getting a broadband upgrade. Out goes last century’s DSL service and in comes gigabit fiber to the home service for villages and towns that American providers would consider unprofitable to serve.

Despite the harsh winter conditions, Altibox has already begun work installing the new fiber network in the fjord and mountain district of Hjelmeland on Norway’s west coast. The aim is to offer a fiber optic connection to each of the 2,800 residents and 1,000 seasonal vacation homeowners who want one by the end of 2016.

Installation has already begun in the fjord and mountain district. The first customers will be online by the first half of 2014. At launch, customers will be offered a package including 1,000/1,000Mbps Internet access, cable TV, and a phone line with calling and feature package for around $165 a month, considered steep for Europe but not unusual in high cost service areas.

With its widely spaced buildings and vacation homes, Hjelmeland is perhaps one of the most challenging districts in Norway to install a fiber-optic network, according to Toril Nag of Altibox.

“This project will set a new standard for what it is possible to achieve when local government, local residents and the service provider all work towards a common goal,” Nag said. “In our assessment, there are currently only a few households that are situated so far from the trunk cable that it would not make economic sense to invest in a fiber connection.”

Not every resident can get broadband service as the district relies heavily on DSL, which underperforms in rural areas. Fiber optics solves the problem distance creates for high-speed copper-based DSL service and is cheaper to maintain in a district known for its difficult terrain and rugged character.

Altibox is using Hjelmeland as a rural broadband laboratory to learn more about how the company can profitably offer fiber optic broadband in higher cost areas. Eventually every Altibox customer across Norway will get gigabit speeds from the provider.

Norway is rushing ahead of North America in broadband deployment and speed. The government has set a target for every resident to have access to a minimum of 100Mbps service by 2017. The European Union has been less demanding, seeking 100Mbps service for at least 50 percent of subscribers by 2020.”We can look forward to an incredibly exciting year,” said Hjelmeland’s mayor, Trine Danielsen. “We believe that the installation of the most advanced data-communications infrastructure in Norway will make us an even more attractive area to live in for people of all ages.

“In the long-term, for example, the fiber-optic network could enable our older residents to live at home for longer, with the help of smart-house technology and new self-help solutions,” she added. “In addition, the new fiber-optic network will boost business development throughout the district, and provide a strong platform on which to build for both existing business enterprises and brand new ones.”

Dr. John Cioffi, the “Father of DSL” doesn’t think much of fiber to the home service, suggesting it is a waste of money and delivers budget-busting losses to providers. He has the ear of the man in charge of overseeing Australia’s National Broadband Network, Communications Minister John Turnbull. Turnbull’s public statements imply he supports Cioffi’s approach – a hybrid fiber-copper network similar to AT&T U-verse.

By adopting cheaper VDSL technology, Cioffi claims providers can avoid the “$800 unrecoverable loss per customer Verizon FiOS has experienced” bringing fiber to the home. He also claims fiber to the home service isn’t as robust as fiber proponents claim, with flimsy, easy-to-break fiber cables and loads of service calls commonplace among some European providers.

Few media interviews, including this one with ABC Television, bother to fully disclose how Cioffi has a big dog in the broadband technology fight. Cioffi founded ASSIA, Inc., a firm that markets products and services to DSL providers. ASSIA is backed by investments from AT&T, its first customer, and a handful of overseas telephone companies. Cioffi estimates ASSIA software is used to manage 90 percent of existing DSL accounts in the United States and is a fundamental part of AT&T’s efforts to increase U-verse speeds. Dismantling DSL in favor of fiber could have a marked impact on ASSIA’s profits.

Australia’s new Communications Minister Malcolm Turnbull talks with Dr. John Cioffi about the differences between VDSL and fiber technologies. Cioffi bashes one form of fiber to the home service dubbed “GPON” because it shares infrastructure. Cioffi claims fiber speeds drop to 20Mbps when a few dozen people share a GPON connection. When in Paris, Cioffi claims his shared fiber connection maxed out at 2.5Mbps while ADSL still ran at 6Mbps. (3:52)

Unsurprisingly, Cioffi claims his company’s software is essential for a good vectored VDSL user experience. Cioffi also claims VDSL can easily beat GPON fiber broadband speeds, a very controversial claim. In Cioffi’s view, even Wi-Fi can perform better than fiber. Finally, Cioffi claims Google is spending $8,000 per customer to deploy its fiber to the home network, when VDSL can do the job for much less money. (2:58)

The Australian government’s proposal to launch a nationwide fiber to the home National Broadband Network (NBN) has been scrapped by the more conservative Liberal-National Coalition that replaced the Labor government in a recent election.

As a result, the Coalition has announced initial plans to revise the NBN with a mixture of cheaper technology that can result in faster deployment of lower speed broadband at a lower cost. If implemented, fiber to the home service will only reach a minority of homes. In its place,  cable broadband may be the dominant technology where cable companies already operate. For almost everyone else, technology comparable to AT&T U-verse is the favored choice of the new government, mixing fiber-to-the-neighborhood with existing copper wires into homes..

Just a year earlier Telstra, Australia’s largest phone company, was planning to decommission and scrap its copper landline network, considered “five minutes to midnight” back in 2003 by Telstra’s head of government and corporate affairs, Tony Warren. Now the country will effectively embrace copper technology once more with an incremental DSL upgrade, forfeiting speeds of up to 1,000Mbps over fiber in return for a minimum speed guarantee from the government of 24Mbps over VDSL.

The turnabout has massive implications for current providers. Telstra, which expected to see its prominence in Australian broadband diminished under Labor’s NBN is once again a rising star. The Liberal-National Coalition government appointed Telstra’s former CEO Ziggy Switkowski to run a “rebooted” Coalition NBN that critics are now calling Telstra 3.0. Communications Minister Malcolm Turnbull also installed three new members of the NBN’s governing board consisting of a Telstra executive, a founder of a commercial Internet Service Provider, and an ex-construction boss who left the NBN in 2011.

ABC reports Communications Minister Malcolm Turnbull asked for the resignations of the entire NBN board, one of the first steps to re-envision the NBN under the Liberal-National Coalition’s party platform. Turnbull accused the former government of setting political targets for fiber broadband and was never forthcoming about the true cost and complexity of the ambitious fiber project. (8:50)

Some Australians complain that NBN’s proposed reliance on Telstra copper is a mistake. Telstra has allowed its landline infrastructure to decline over the years and many are skeptical they will ever see faster speeds promised over wiring put in place decades earlier.

The NBN under the Liberal-National Coalition will depend heavily on two copper-based technologies to deliver speed enhancements: VDSL and vectoring. Both require short runs of well-maintained copper wiring to deliver peak performance. The longer the copper line, the worse it will perform. If that line is compromised, VDSL and vectoring are unlikely to make much difference, as AT&T has discovered in its effort to roll out faster U-verse speeds, much to the frustration of customers that cannot upgrade until AT&T invests in cleaning up its troubled copper network.

Coalition critics also warn the new government will foolishly spend less on a fiber-copper network today that will need expensive fiber upgrades tomorrow.

Turnbull isn’t happy with Australia’s mainstream media for lazy reporting on the issues.

ABC Radio reports that the Coalition’s approach to the NBN may be penny-wise, pound foolish. By the time the NBN rolls out fiber to the neighborhood and Telstra is required to invest in upgrades to its copper network to make it work, fiber to the home service could turn out to have been cheaper all along. (5:11)

“I have to say that by and large the standard of reporting of technology and broadband by the mainstream media has been woeful,” Turnbull said. “If the Australian public are misinformed about these issues, it was in large part a consequence of the unwillingness of the mainstream media to pay any attention to what is really going on in the industry.”

The promise of fiber optic broadband may prove elusive under the new government.

With much of the new NBN dependent on Telstra’s copper telephone network, Stuart Lee, Telstra’s managing director of its wholesale division, rushed to defend the suitability of the same copper network Telstra was prepared to scrap under the last government.

Lee said he was especially annoyed with critics that call Telstra’s copper networking “aging.”

“The other thing that makes me cross when I hear it, and I see it a lot in the press is the talk of the aging copper network. It’s not. It’s not an aging copper network. It’s like grandfather’s axe; it’s had five new handles and three new heads. When it breaks, we replace the broken bit. So it’s much the same as it always has been and always will be,” Lee said. “It’s just an older technology, it’s not that the asset itself has deteriorated.”

When questioned about several recent high-profile mass service disruptions Australians experienced on Telstra’s landline copper network, Lee blamed the weather, not the network.

“They correlate to weather events, and the weather events we’ve had in the last [few years] is about five to six times the previous ones, so surprise surprise there is a lot more damage,” said Lee.

The new government has charged the Labor-run NBN with inefficiency, taxpayer-funded waste, and playing politics with broadband by giving high priority to fiber upgrades in constituencies served by threatened Labor MPs. Lee added NBN Co has played loose with the facts, declaring premises “passed” by the new fiber network without allowing customers to order service on the new network. That can become a serious problem, because the NBN plan calls for customers’ existing copper phone and DSL service to be decommissioned soon after the fiber network becomes available.

The Sydney Morning Herald compared the last Labor government’s broadband policy with the new Coalition government policy.

iiNet’s chief technology officer, John Lindsay said that the potential for disconnecting customers from the ADSL network while they still can’t order NBN service was “madness.”

The Labor government’s NBN has also been under fire for a pricing formula that includes a usage component when setting prices. Impenetrably named the “connectivity virtual circuit” charge, or CVC, the NBN charges retail providers a monthly connection fee for each customer and a usage charge that includes a virtual data allowance originally set at 30GB. Retail providers are billed extra when customers exceed the informal allowance. Although the government promised to reduce the charges, they effectively haven’t and likely won’t until 2017.

Lindsay called the CVC an artificial tax comparable to the Labor government’s carbon tax, and represents a digital barrier to limit customer usage.

“It’s a tax on packets,” Lindsay said.
