Product Description

12CH CWDM Demux

GEZHI 12CH CWDM Demux based on dielectric thin-film filter technology which with insert type ABS box package connect by LC/UPC adaptor. The wavelength of 12CH CWDM Demux is from 1271nm to 1571nm, transmission on a single optical fiber with only 3dB link insertion loss. The 12CH CWDM Demux has high channel isolation and can therefore be used in a bi-directional system. The module can be used as a multiplexer or de-multiplexer.

This 18CH CWDM mux demux is a game-changer! The monitor port is super practical for power checking, TFF tech makes it run super stable, and the low insertion loss is exactly what I needed for my data center. Shipped fast too!
