After 6 months, technical team has developed this ultra-compact module, which is very small in size, only 21x15.5x6.5mm. 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.
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.
provides a complete portfolio of CWDM Mux Demux and Optical Add Drop Multiplexer (OADM) units to suit all applications such as: Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV. And we provide optional port configurations such as: Express Port, Monitor Port, 1310nm passband port and 1550nm port for these multiplexers according to customer choice.
