Expandable 4-Channel Single Fiber Passive O-band Mux/Demux Description

4 Channels Single Fiber Passive O-band Mux/Demux – SOMD-4B-L is a member of the EDGE Optics xWDM Series product line. We designed EDGE Optics xWDM Series products to allow easy, gradual, logical, and cost-efficient expansion of network bandwidth using industry-leading passive WDM technology. The main advantage of xWDM is its passive nature – no power supply or cooling necessary, robustness with no special micro-climate requirements, and as a passive element, it has an MTBF of 100+ years. xWDM is fully data rate and line protocol neutral – it is possible to use with colored transceivers supporting applications such as 100G Ethernet. It is simple to install and requires no configuration or maintenance. SOMD-4B-L is a passive multiplexer/demultiplexer package designed to organize 4 duplex, protocol-independent O-band LAN-WDM 200 GHz grid compatible data streams over a single strand of single-mode fiber. The unit features LC/UPC connectors. With a focus on minimal insertion loss, SOMD-4B-L is equipped with band-pass filters extending the maximum distance of O-band connections. SOMD-4B-L is manufactured as an LGX-type package, installed in a 19" 1U sub-rack fitting any standard equipment rack. SOMD-4B-L is used together with the counterpart SOMD-4A-L module at the other end of the line. The 1% monitor port ensures easy troubleshooting without downtime.
