After 6 months, technical team has developed this ultra-compact module, which is very small in size, only 28x22.5x6.5mm. For six months, the technical team continued to modify the drawings, packaging structure, and packaging materials, and finally made the same CWDM able to withstand the test of extreme environments with the smallest size. The ultra-compact CWDM module is available with 4, 8, 16, and 18 channels, and has the advantages of high isolation, low loss, and high stability.

we are the only manufacturer capable of producing UC-WDM Devices in the entire optical communication market.

CWDM Mux/Demux is a passive technology, it allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. T1 over fiber at 1570nm transported alongside 10Gbps Ethernet at 1590nm). This allows for long-term future proofing of the networking infrastructure because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed.
