Customer Reviews
We'd like to give five stars. Bought this product for deploying a DWDM network. The insertion loss is low indeed. Very efficient transmission and saved us a great bunch of fibers.

—— Charles Keith

The switch is very easy to use and can work well in the cross connection. Good quality.

—— Daniel Miller

We always got their timely replies for our CWDM issues. The 18CH mux performed cool for our 10Gbps data.

—— Pavel Yailo

The final solution meets our demands for CWDM and monitoring. We are satisfied.

—— Alexander

Very nice MUX with low insertion loss, greatly reducing my link insertion loss

—— Frank Bozich

This MUX is customized according to my requirements strictly, perfect!

8CH Fiber CWDM Module


1610nm CWDM Passive Multiplexer


1x8 Coarse WDM


8CH 1470~1610nm CWDM Passive Multiplexer ABS Box type Coarse WDM


GEZHI’ 8CH 1470~1610nm Passive CWDM Mux or Demux Module in Optical Transport Networking System utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides high channel isolation, low insertion loss, wide pass band, low temperature sensitivity and epoxy free optical path. Our CWDM Mux Demux products provide up to 16-channel or even 18-channel Multiplexing on a single fiber.


Due the the low insertion loss is needed in WDM networks, we can also add “Skip Component” in a CWDM Mux/Demux module to reduce the IL as an option. Standard CWDM Mux/Demux package type include: ABS box package, LGX pakcage and 19” 1U rackmount.
