Product Profile

This 8 Channel CCWDM Mux Demux utilizes free-space optics technology and is a passive wavelength division multiplexing (WDM) device suitable for short-distance transmission, high density, and low loss. Integrating a multiplexer and demultiplexer, it enables efficient multiplexing and demultiplexing of 8 CWDM wavelength signals, supporting passive transparent multiplexing for any rate and any service without additional configuration, seamlessly adapting to the transmission needs of various service signals.

This CCWDM module is widely compatible with 1G/10G/25G Ethernet, multi-rate fiber channel, SDH/SONET, FTTx, and CATV services. Leveraging its passive transparent multiplexing characteristics, it can flexibly support various rate services without requiring additional signal processing. Furthermore,the 8 Channel CCWDM Mux Demux can be paired with CWDM optical modules and OADM modules to flexibly build diverse network topologies such as point-to-point and ring networks, offering flexible networking options and strong overall adaptability.

Compared to traditional CWDM, this CCWDM module has a more compact structure, higher integration, lower insertion loss, and superior optical path performance and channel consistency, effectively saving fiber optic cabling resources and enabling low-cost optical network expansion and upgrades.
