XO Communications said Monday it has increased the capacity of its core network by 200 percent by deploying an additional 800gbps of capacity on major routes across its18,000 route-mile optical network.

The company also said it has extended the availability of its 3 Guarantee Program, which offers carriers, cable companies, content providers, enterprises and wireless companies incentives to leverage its transport platforms, including Ethernet, IP transit and wavelength services.

XO will light two new fiber strands on its nationwide fiber network adding 800gbps of capacity in core network nodes, which will deliver an additional 80 10gbps channels on major coast-to-coast network routes. XO has contracted with Infinera Corp. to implement the upgrade using the Infinera DTN system.

XO implemented the Infinera system last year with the initial expansion of its network.

Under the 3 Guarantee Program, XO said it will offer best price and install guarantees and a 90-day trial for its services.
