XO Communications Selects Infinera for Advanced 18,000-Mile Optical Network

"Digital Optical Network" Enables New Services, Doubles Capacity

SUNNYVALE, CA -- (MARKET WIRE) -- March 20, 2006 -- XO Communications (OTC BB: XOHO) has selected Infinera's DTN optical system for a major network upgrade to significantly expand their network capacity and enable XO to offer a wide array of new high-capacity services.

Based in Reston, Virginia, XO is one of the nation's largest service providers, with an 18,000-mile national fiber optic long haul network connecting more than one million miles of metro fiber and serving 75 metropolitan areas across the United States. XO will deploy the Infinera DTN, with its Digital Optical Networks architecture, to double network capacity, speed service delivery, enable new service offerings in existing metropolitan areas, improve reliability, and ease network management.

"XO's transformation to digital fiber optics will yield a quantum leap in the management and performance of our network," said Randy Nicklas, vice president of engineering at XO Communications. "Rising market demand for high-capacity IP-based transport services requires faster response times to deliver capacity when and where customers need it. This major initiative optimizes the value of our network investment, and empowers XO to pursue new opportunities that will drive revenue."

The Infinera DTN optical platform is the first telecommunications system based on photonic integrated circuits (PICs). It combines the scalability of Dense Wave Division Multiplexing (DWDM) with the flexibility of digital switching and power of GMPLS service intelligence. The Infinera DTN was selected by XO because of numerous features and capabilities unavailable from any other DWDM-based optical system, including:

--  Simple, Fast, and Easy Deployment: The Infinera DTN's digital
    architecture and software intelligence makes it fast and easy to deploy,
    with little of the tweaking and "fine tuning" required by conventional
    optical systems. Consequently, XO expects that its entire 18,000-mile
    deployment will be complete by the end of the third quarter.
--  Unconstrained Add/Drop: The Infinera DTN allows XO to add/drop
    transport services at any DTN location simply and economically.  Both wave
    services and "sub-lambda" services can be dropped without the restrictions
    typical of ROADM-based solutions.
--  Fast Service Delivery: The Infinera DTN supports GMPLS routing for
    automated creation of services across a network.  XO will use Infinera's
    GMPLS to create circuits, even from coast-to-coast, in a matter of seconds,
    without manual intervention at intermediate network locations.  XO will
    also gain the benefit of Infinera's recently announced Just-In-TAM™
    program which provides for rapid delivery of Infinera's TAM  line cards,
    used at the two ends of a network link, to enable provisioning services in
    as little as ten days.
--  New Service Types: Infinera's flexible hardware allows XO to offer
    numerous services without numerous equipment types.  XO plans to use the
    Infinera DTN network to offer 2.5G and 10G wave services, OC-192 private
    lines, and Gigabit Ethernet, 10GbE, and 40GbE services.  The Infinera DTN
    will allow XO to offer protected and unprotected options as well to best
    meet the needs of a variety of customers and applications.  Infinera's
    Digital Wrapper technology means all services, whether SONET, Ethernet, or
    wavelength, are both transparent and robustly managed end-to-end.
"We are thrilled to be selected by XO for their new national network," said Jagdeep Singh, Infinera co-founder and CEO. "The advanced features and functionality, as well as the superior economics of the Infinera DTN, based on large-scale photonic integration, will help XO gain a competitive advantage in the marketplace."
