Each tiny light represents a single strand of optical fiber.

Verizon has achieved speeds of more than 1.5Tbps as part of a joint field trial with NEC Corporation of America.

The two companies conducted the trial across 2,212 miles of fiber in the Dallas area, successfully demonstrating three separate channels of data streams co-existing on just on a single strand of fiber.

“As we look to a future when data rates go beyond 100G, it’s important to begin examining how these technologies perform,” said Glenn Wellbrock, director of optical transport network architecture and design at Verizon. “This trial gives us a good first step toward analyzing the capabilities of future technologies.”

Verizon’s test placed three different high bit-rate data streams on a single strand of fiber.  Each respective “superchannel” ran at different speeds — 100Gbps, 450Gbps, and 1000Gbps — at the same time, with no significant degradation.

To put that in context, Google’s Fiber to the Home project in Kansas City, Kansas will operate at 1Gbps.  It would take more than 1,500 users fully saturating their Google Fiber connection to utilize the same amount of bandwidth Verizon demonstrated on just one fiber strand.  With most fiber projects bundling many strands of fiber into a single cable, near limitless capacity can bring a broadband experience untroubled by high traffic, high bandwidth multimedia applications.

Previously, Verizon had proven its fiber technology for high bit rate applications in a lab environment.  This was the first “in the field” trial over a functioning fiber network concurrently serving customers in Dallas.

Such technology demonstrates that as broadband traffic grows, so does the technology to support it.
