Light-Plex Module Outdoor Plant OP4538x Series


OP4538 series Light-Plex modules provide a combined narrowcast demultiplexer with a broadcast/narrowcast combiner. Each OP4538 demultiplexes up to eight DWDM wavelengths and is available in various wavelength combinations. The OP4538 features four optical input ports (one carrying the DWDM narrowcast services for up to 40 ITU-grid optical channels and the remaining three for either a single eight-way split or dual four-way splits of broadcast services). Of the nine output ports, eight provide the combined output of the split broadcast signal and one of the eight demultiplexed narrowcast channels (via a common, industry-standard MPO style connector), and the remaining port provides a pass-through of narrowcast channels not demultiplexed by the unit.

Due to the very low insertion loss of their optical filters, up to three OP4538s can be installed in a single VHub with their DWDM narrowcast passthrough signals cascaded from one unit to another, resulting in a single VHub capable of service to up to 20,000 homes.
