Passive Optical DWDM system Mux Module 200Ghz Multiplexer and Demultiplexer
GEZHI DWDM MUX DEMUX Modules with 50GHz/100GHz/200GHz channel spacing can be used to combine or separate wavelength channels at standard ITU grid. We supply the common configuration including 2, 4, 8, 16, 24, 32, 40, 44, and 48 channels.
These DWDM modules passively multiplex the optical signal outputs from 4 or more electronic devices, and send them over a single optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices at the other end of the fiber optic link.
Our standard package types of DWDM MUX DEMUX are Field Module ABS Plastic Box, 19" Rack Mount Chassis and LGX Metal Cassette Box. We also supply custom package to meet customers' requirements. All the DWDM MUX DEMUX modules provide excellent optical performance and high reliability to ease of fiber handling and power saving solution
Duplex DWDM MUX & DEMUX
Multiplexer (MUX) and demultiplexer (DEMUX) are combined together into a single piece of equipment for bi-directional data transmission over two fibers.
