XO Communications will upgrade its nationwide IP/MPLS network using the Cisco IP Next Generation Network (IP NGN) architecture to meet the growing demand for high-speed Internet access services and support its expansion into the high-capacity IP Transit services market. 
The expansion will more than double current capacity and sets the stage for a four-fold increase. Specifically, XO will deploy the Cisco CRS-1 Carrier Routing System in the core of its nationwide IP/MPLS network.

- In October, XO Communications completed an 800 Gbps capacity upgrade on major coast-to-coast routes of its nationwide fiber optic network. The upgrade delivers an additional 80 10-Gbps channels on major coast-to-coast network routes. This additional network capacity augments a capacity expansion XO completed last year which delivered 400 Gbps of capacity across the XO network. The upgrade is being delivered on Infinera's DTN system, which XO implemented last year with the initial expansion of its network.
