US service provider Verizon is claiming another 100G first, with the deployment of 100G on an ultra-long-haul section of the company’s US backbone – essentially delivering on a promise made earlier this year.  More significantly, the company says it plans to increase the number of routes using 100G technology to 10 by the end of the year, rather than just the three that were announced back in March.


“We've reached the inflection point where 100G makes sense from a network perspective as well as a technology and a cost perspective,” claimed Ihab Tarazi, vice president of global network planning at Verizon.  
According to Verizon, the big push for deploying 100G comes from the need to reduce latency – the time it takes for data sent from its entry point in the network to reach its destination – as well as the increase in capacity per fibre and better transmission economics.
“We're seeing not only growth in traffic, but also in the need for immediacy from our customers that are managing financial transactions, health care data exchange, energy services and entertainment on-the-go,” said Tarazi. “With 100G, Verizon will be able to help meet those demands more efficiently and with better performance.”
Verizon is deploying advanced transmission equipment from Ciena, which uses dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection.  Verizon has worked closely with its suppliers on 100G over a number of years, including Nortel, which developed the 100G technology that was later sold to Ciena.  Nortel and Verizon lit up the first commercial 100G link in Europe, between Paris and Frankfurt, in 2009.
“Verizon has been a clear leader in pushing 100G technology for years now, so their enthusiasm for pushing forward shouldn't be a huge surprise,” wrote Bo Gowan, Ciena’s social media manager. “Even so, when one of the world's largest network operators says 100G has hit an inflection point and backs that opinion up with immediate plans for further 100G deployments, you tend to take notice.”
