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!

8 Channels CCWDM Mini Module Free Space Cascading Technology



GEZHI specialized in custom configured, reliable, CCWDM products based on customer requirements. Our Low insertion loss Compact CCWDM (CCWDM) Module is based on Free Space Optics & has better uniformity versus Thin-Film Filter (TFF) designs. GEZHI's High Isolation, low PDF CCWDMs offer high quality parameters up to 18 channel solutions and can include a 1310nm upgrade port and test/monitor ports as well.

It can replace CWDM Products are used in telecommunications, corporate networks, PON networks, cable TV and other fields. The lower insertion loss makes the CCWDM module have lower signal attenuation when used, thereby reducing the power requirements of the signal transmitter.

Unique Free-Space Technology
The 8 Channels CCWDM Mini Module adopts Free-Space technology, which uses light propagating in free space to wirelessly transmit data. Inside the device, adjacent signal channels are cascaded by parallel beam instead of the fiber. This saves a lot of space for package box, and the unique workmanship also helps CCWDM Mux Demux with low insertion loss.
