Product Details
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.
