WDM Coupler 980/1550nm - Fused Fiber

 

WDM (wavelength division multiplexing) pump coupler multiplexes pump laser powers at 980nm and optical signals at 1550 or 1590nm into Erbium doped fiber in an optical amplifier. Usually 980/1550nm WDM couplers are used in C band EDFAs, while 980/1590nm WDM couplers are used in L band EDFAs. These couplers are fabricated using special fibers such as Corning HI 1060 Flex or OFS BF05635-02 fiber to ensure their high quality and performance. The typical insertion loss of our premium grade 980/1550nm WDM couplers is less than 0.10dB. With high stability and reliability, this product is an ideal component to be used in optical amplifiers prototyping, testing and manufacturing.

Features:

• Low insertion loss


• Low PDL


• High wavelength isolation


• High stability and reliability


• RoHS compliance

Applications:

• C or L band Erbium doped fiber amplifiers


• Pump laser power rejection
