These L-Band Supervisory Channel WDM devices use stable Thin Film Filters and advanced packaging technology to achieve good performance and excellent environmental stability.
These L-Band Supervisory Channel WDM devices use stable Thin Film Filters and advanced packaging technology to achieve good performance and excellent environmental stability. The devices is used to add or drop supervisory. It provides low insertion loss, high channel isolation, low PDL and low temperature sensitivity.These components have been extensively used in high power optical amplification systems and FTTH systems, CWDM systems or DWDM systems.
