C L Band FWDM WDM Wave Division Multiplexing Module Multipurpose
Optical Passive Components WDM Module C-L Band FWDM
These C/L Band Filter Wavelength Division Multiplexer (C/L Band WDM) devices use stable Thin Film Filters and advanced packaging technology to achieve good performance and excellent environmental stability. The devices combine or separate light at different wavelength in a wide wavelength range. They could be used to combine or separate Red band wavelength signals and Blue band wavelength signals in C band range, or C band wavelength signals and L band wavelength signals in DWDM systems. It provides low insertion loss, high channel isolation, low PDL and low temperature sensitivity.These components have been extensively used in FTTH systems, CWDM systems or DWDM systems. The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
