Verizon Business completes 100G trial with U.K. research and education network

MAY 27, 2009 -- The field trial with JANET moves high-bandwidth optical service closer to commercial deployment.

MAY 27, 2009 -- Verizon Business (search Lightwave for Verizon Business) has reported completing a successful trial of 100-gigabit optical service with JANET, the United Kingdom's National Research and Education Network.

The field trial, completed in April, is the latest in a series of successful trials conducted by Verizon, which is aggressively working with major equipment suppliers toward 100G commercial deployment. Typical optical carrier network speeds are 10G and 40G.

Using a 103-km section of the Verizon global network between London and Reading, the trial with JANET demonstrated that 10-, 40-, and 100-Gbps optical signals can be carried simultaneously without signal impact. This conclusion signifies that current networks can be upgraded to the higher bandwidth without modification to the physical network, providing a faster, more economical implementation.

"Moving toward reliable, high-performance 100G technology is critical, especially for organizations like JANET that support education and research projects requiring significant bandwidth," says Ihab Tarazi, vice president of global network planning for Verizon.

JANET is a private network comprising a backbone and 19 regional networks, connecting universities, colleges and schools as well as research councils.

During the 100G trial with JANET, test equipment was used to deliberately introduce signal impairments, which were then corrected by electronic hardware. The results showed 100G service can provide more than twice the tolerance of conventional 10G signals for several key parameters as well as a more robust transport system at 10x the data transmission rate.

"Our goal is to progress as quickly as possible to the delivery of 100G technology but with the level of performance and reliability required by our customers," says Tarazi. "This latest trial shows Verizon can definitely meet the requirements of the world's most data-intensive customers and it moves us another step closer to commercial deployment."

In October 2008, Verizon and Nortel (search Lightwave for Nortel) proved 100G transmission could perform with better tolerance for signal distortion than typically found in today's standard 10G wavelength (see "Verizon, Nortel announce 100G trial"). A month earlier, Verizon and Nokia Siemens Networks (search Lightwave for Nokia Siemens Networks) announced they had successfully transmitted data at 100G on a single wavelength for more than 1,040 km, setting a new distance record over deployed fiber and demonstrating better performance than conventional transmission (see "Verizon, Nokia Siemens Networks claim new record for 100G transmission"). In November 2007, Verizon and Alcatel-Lucent (search Lightwave for Alcatel-Lucent) transmitted a commercial information package -- a FiOS video stream -- between Tampa, FL, and Miami at 100G for the first time over a live network (see "Verizon completes 100-Gbit/sec field trial").
