Product Details
100Ghz Fiber Optical DWDM mux and demux Module with 1U Plug-in
Rackmount
The GEZHI Photonics 8-channel DWDM multiplexers and demultiplexers
facilitate DWDM architectures. Each 8Channel DWDM multiplexes up to
eight DWDM wavelengths. Of the nine input ports, eight accept the
inputs of individual narrowcast signals (via a common, LC/SC/FC or
MPO connector), and the remaining port accepts the multiplexed DWDM
input from prior modules in a cascade. The DWDM output port carries
the combined, multiplexed signal of all narrowcast channels, and a
monitoring port is also available.
The GEZHI Photonics' 8channel DWDM demultiplexer operates in
comparable fashion, but in this case serving to output the
individual (up to eight) DWDM signals from a single DWDM input
port, and any remaining narrowcast signals passed through a DWDM
out cascade port.
