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!

FTTX Filter WDM module extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation is based on Thin Film Filter (TFF) technology. The device combines or separates light at different wavelengths in a wide wavelength range. It can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
GEZHI Photonics provides filter-based wavelength division multiplexing (WDM) filter devices that are customized to the particular wavelength bands for your special applications. As you might know, GEPON system itself works on 1310/1490, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get's "mixed".
