PM Filter WDM 980-1064, 1030-1064, 980-1550, 1550-1064,1480-1550nm
Description
The PM Fliter Wavelength Division Multiplexer combines two different wavelength into one fiber, based on environmentally stable thin film filter technology. The PM FWDM is designed mainly for EDFA, Pump lasers,commucation system,characterized with high isolation, low insertion loss, high return loss, excellent environmental stability ,high power handling capability and wide band.
