1260nm~1620nm Polarization Maintaining Coarse WDM for CWDM/OADM Networks
Product Overview
The Polarization Maintaining Corse Wavelength Division Multiplexer Filter is designed and manufactured to international standard. The devices use environmentally stable thin film filter 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 function or can be cascaded into sequence for multi-channel applications in CWDM systems. It is also used to block out unwanted noise signals in EDFAs and fiber laser systems.
The components are characterized with high isolation, low insertion loss, high extinction ratio, excellent environmental stability and high power handling capability.
