Product Profile

This Mux Demux 18CH CWDM is a standard 1U rack-mount passive device with pigtails. It functions as both a multiplexer and demultiplexer, supporting both wavelength multiplexing and demultiplexing. Utilizing a single fiber, it enables simultaneous transmission of 18 different wavelength signals, significantly improving fiber utilization and reducing cabling costs. The CWDM employs a half-path adhesive-free optical path technology, exhibiting excellent performance characteristics such as polarization insensitivity, high isolation, low crosstalk, low insertion loss, and low temperature drift, ensuring stable and durable operation.

This Mux Demux 18CH CWDM comes standard with LC/UPC interfaces and also supports customization of other interface specifications, providing customized solutions based on customers' actual application needs. It comprehensively covers the entire standard CWDM band from 1260nm to 1620nm, offering excellent compatibility and widely adapting to various service transmission scenarios including 1G/10G/25G Ethernet, SDH/SONET, 1/2/4/8/16G Fibre Channel, FTTx, and CATV.
