OnFiber Communications has deployed the Infinera DTN optical platform for DWDM and bandwidth management in multiple metro optical networks throughout the United States in support of wavelength, Ethernet and SONET services.
This is the first metro specific deployment of the DTN system, which was introduced in spring 2004.
Last month, wholesaler Level 3 Communications Inc. announced it will upgrade the capacity of its optical network in the United States and Europe using Infinera’s system. The carrier plans to complete the overbuild of a majority of its North American long-haul network by the end of the year
Level 3 is the first major carrier in the United States to deploy DTN. German carrier freenet selected the system earlier in the year.
DTN is the first optical telecom system based on photonic integrated circuits (PICs), which enable multiple wavelengths of light, carrying hundreds of gigabits per second of traffic, to be managed digitally, rather than as analog waves. In contrast, conventional WDM products, built without the benefit of PICs, use analog techniques for many networking functions.
OnFiber selected Infinera’s DTN for its ability to quickly turn up high-speed services and to simplify optical engineering and operations.
“OnFiber’s customers require high bandwidth solutions delivered quickly and with rock solid connectivity,” says OnFiber CEO Danny Bottoms. “Our success comes from the fact that we can provide very high levels of flexibility, speed, and service quality. The advanced technology of the Infinera DTN is an important component of our total network solution package.”
DTN is now carrying live traffic for OnFiber. It supports 800gbps of DWDM capacity and delivers a variety of manageable and protectable SONET/SDH and Ethernet-based services, including 10 gigabit Ethernet LAN PHY.
