The low growth in bridge/routers reflects dwindling demand for equipment that converts Fibre Channel into wide-area protocols like ATM (asynchronous transfer mode). Growing numbers of SANs will run Fibre Channel directly over wavelengths furnished by DWDM (dense wavelength-division multiplexing) equipment.
"It's really an issue of network design. There's no change to the signal involved. All we have to do, basically, is assure that the power levels are the same between the Fibre Channel and DWDM boxes by adding or subtracting attenuators," says Todd Bundy, director of business development at Adva AG Optical Networking (Neuer Markt: ADV).
Adva is one of several DWDM vendors that have announced SAN compatibility for their products. Others include LuxN Inc., Nortel Networks Corp. (NYSE/Toronto: NT), ONI Systems Inc. (Nasdaq: ONIS), and Sorrento Networks Corp. (Nasdaq: FIBR).
