The OCM 1891 is a compact CWDM passive 9 channel optical multiplexer / de-multiplexer designed to send / receive up to 9 individual signals over a single fiber link. Supports unidirectional and bidirectional applications. The module features an UPG (Upgrade) port to connect to the OCM 1892, which expands the total capability to 18 channels in a single fiber link.



The modules can be used standalone or integrated into the optional RFR 1018 0.5 RU 19” rack frame, ideal for system installations.



Ideally suited for use with the ORX 1800, ORR 1802 receivers / OTX 1840, OTT 1812 CWDM transmitters / OTR 1840 CWDM transceiver and the OET 1540 Ethernet Transceiver (all 18 wavelengths available as specified in ITU-T G.694.2)



The OCM 1891 supports the following wavelengths: (ITU-T G.694.2) 1270,1290,1310,1330,1350,1370,1390,1410,1430nm
