Extreme Networks plans to use technology from optical component maker MRV Communications to speed up its strategy for high-speed networks. MRV plans to supply Extreme with fiber-optic technology the company will add to its current line of high-speed switching devices. It also plans to use the technology within a soon-to-be-released set of equipment targeted at optical networks in metropolitan areas and Internet service providers (ISP), according to the company. Extreme first targeted businesses with its high-speed switches, but has recently said it would alter its strategy to include technology for ISPs and metropolitan networks. Other upstarts in the networking business, such as Foundry Networks and Sycamore Networks, have reaped huge Wall Street gains for a similar high-end focus. The company has been working with MRV on the technology for about six months, according to an Extreme executive.
