The Polarization Maintaining Coarse Wavelength Division Multiplexer Filter is designed and manufactured to international standards. These devices utilize environmentally stable thin film filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, and excellent environmental stability.
They can be used individually to perform single channel add or drop functions, or cascaded in sequence for multi-channel applications in CWDM systems. They are also employed to block unwanted noise signals in EDFAs and fiber laser systems.
The components are characterized by high isolation, low insertion loss, high extinction ratio, excellent environmental stability, and high power handling capability.
