WDM (wavelength division multiplexing) pump coupler multiplexes pump laser powers at 1480nm and optical signals at 1550 or 1590nm into Erbium doped fiber in an optical amplifier. Usually 1480/1550nm WDM couplers are used in C band EDFAs, while 1480/1590nm WDM couplers are used in L band EDFAs. The typical insertion loss of our premium grade 1480/1550nm WDM couplers is less than 0.15dB and isolation greater than 18dB.
With high stability and reliability, this product is an ideal component to be used in optical amplifiers prototyping, testing and manufacturing. This product has passed the Telcordia 1209 and 1221 tests.
