Description
1590 980nm High Power PM Tap Isolator WDM Hybrid
1590 980nm High Power PM Tap Isolator WDM Hybrid is a fiber passive component which integrated with the function of Tap Filter Coupler, Optical Isolator and WDM, Tap Coupler can separate the signal power for monitoring, Optical Isolator for avoiding the backward reflection light, WDM can combine pump light and signal light. It’s widely used in EDFA and Fiber Amplifier application, higher power type is available upon request.
