Product Description

18CH CWDM Mux Demux Module 1270~1610nm low loss BIDI CWDM

GEZHI 18CH low loss BIDI CWDM based on dielectric thin-film filter technology which designed for integration in low cost access and metro networks. GEZHI 18CH CWDM is an optical multiplexer that can multiplex up to 18 CWDM sources on a single optical fiber with only 3.5dB link insertion loss. Its package by 120*80*18mm ABS box with 900um loose tube, 1meter, COM-SC/UPC connector, other output with LC/UPC connector. The 18CH CWDM filter 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 and uses a single slot in a frame or can be used, standalone, in an N-box.

I ordered just 1 piece for a test, and it exceeded all my expectations! The wavelength accuracy is spot-on, the hybrid CWDM-DWDM function is a huge plus, and customer service was super helpful with my OEM questions.

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!
