Simplex CWDM MUX and DEMUX
Multiplexer (MUX) and demultiplexer (DEMUX) are combined together into a single piece of equipment for bi-directional data transmission over one fiber.
Simplex Bi-Directional Transmission should be used in pairs, MUX/DEMUX Portfor specific wavelength must be opposite CWDM
HJY 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.
HJY 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.
