These L-Band Red/Blue Pass Filter WDM devices use stable Thin Film Filters and advanced packaging technology to achieve good performance and excellent environmental stability.
These L-Band Red/Blue Pass Filter 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 L band range 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.
