The ARRIS OP45M8x and OP45D8x series 8-channel DWDM multiplexers and demultiplexers facilitate DWDM architectures. Each OP45M8x multiplexes up to eight DWDM wavelengths. Of the nine input ports, eight accept the inputs of individual narrowcast signals (via a common, industry-standard female MPO style 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 -20 dB tap of the DWDM output signal provides a convenient test point.
The OP45D8x demultiplexer operates in comparable fashion, but in this case with the MPO connector 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. In this case the -20 dB test point is used to monitor the signal on the input port of the module.
