XO Adding 1.6 Tbps Nationwide Capacity with Infinera

XO Communications is embarking on its third nationwide network upgrade, which will more than double the capacity of the XO inter-city transport network. XO is using Infinera's ILS2 line system to deploy the ultra-long-haul nationwide network expansion, which will deliver 160 wavelengths on a single fiber and create 1.6 Terabits/second (Tb/s) of additional optical capacity. The network upgrade is expected to be complete later this year.


XO said the boost to its ultra-long-haul network enables it to meet the increasing demand for high-capacity network transport solutions from carriers, service providers and large enterprise customers. The upgrade will also support XO's Carrier Services network transport offerings, including its "Carrier Wavelength FLEX" promotion and its "10 Gigs in 10 Days" carrier service guarantee. Using the GMPLS-powered service intelligence in Infinera's IQ network operating system, XO Communications will be able to provision any service, currently from 1 Gbps to 40 Gbps and up to 100 Gbps in the future, between any two points on the network in 10 days or less.


XO Communications entered the United States' long-haul market when it deployed the first-generation Infinera DTN system in 2006.

In 2007, XO Communications again expanded its core transport network, deploying an additional 800 Gbps of capacity on major coast-to-coast routes across the United States. The current Infinera DTN system is the only DWDM system with 160 wavelengths in the C-band and is scalable to 8 Tbps in the future.


XO noted that it has invested more than $450 million to enhance and expand its network infrastructure, services portfolio and systems -- including its long-haul, metro, data and IP and interconnection networks -- resulting in a network footprint that now reaches nearly half of all businesses in the United States.
