8CH CWDM Fiber Optic Modules
The 8CH CWDM Fiber Optic Modules is designed and manufactured to Telcordial standard. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve a wide pass band, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop functions or can be cascaded into sequence for multi-channel applications in CWDM systems.
