PM Fiber DWDM Filter – 1 x 2
Description
The PM Dense Wavelength Division Multiplexer is manufactured toTelcordia standard, based on environmentally stable thin film filter technology. The PM DWDM is designed mainly for signals adding/dropping on OADM, and Mux/Demux DWDM commucation system,with the advantage of high isolation, high extinction ration, low insertion loss, excellent environmental stability, and high power handling capability
