Richmond, Virginia — June 7, 2010 — Intellifiber Networks, serving the growing network needs of enterprise, service provider and government markets, today announced it has partnered with CENX, operator of the world’s first and most connected Carrier Ethernet exchange, to provide expanded Ethernet services to service provider customers. Through an initial connection at CENX’s New York location, Intellifiber will offer its services, including Ethernet over Copper (EoC) connectivity, and have access to CENX-connected providers.

“Ethernet services continue to be a rapidly growing market segment, and our partnership with CENX allows Intellifiber and CENX members to broaden Ethernet adoption,” said Clint Heiden, president of Intellifiber Networks. “We can deliver cost-effective Ethernet services to more than 100,000 buildings across our network to any CENX-connected location around the world. CENX’s expertise and global Ethernet reach were key factors in our partnering decision.”

Through CENX, Intellifiber will offer its full suite of Ethernet products, including Ethernet over Copper connectivity in its coverage area. Intellifiber has more than 300 central offices directly connected to its fiber network, providing dense EoC coverage in markets from Norfolk to Philadelphia to Cleveland to Richmond. EoC allows Intellifiber to leverage existing copper infrastructure to cost effectively deliver midband Ethernet access directly to customers without having to match demand to legacy circuit sizes.

“We are delighted to welcome Intellifiber into our rapidly growing CENX membership. Our focus is to simplify and enable expanded carrier Ethernet growth for our exchange members by eliminating the cost and complexity of direct service connections,” said Eric Gillenwater, vice president, Worldwide Development, CENX. “Connecting with CENX immediately creates an even more extensive footprint while allowing all of our members the opportunity to seamlessly purchase Intellifiber’s services.”
