Optical Transponder (O-E-O) Used in WDM Network
WDM technology is commonly used in today’s optical networks. It basically assigns each service (10G LAN, SONET/SDH, Fiber Channel, etc) an independent dedicated wavelength—which then is multiplexed into one single fiber. Eliminating the use of multiple fibers while increasing fiber … Continue reading
