The OCM 1891 is a compact CWDM passive 9 channel optical multiplexer/demultiplexer designed to send or receive up to 9 individual signals over a single fiber link. The module has an UPG (Upgrade) port to connect to the OCM 1892, which expands the capability to 18 channels. The modules can be used standalone or integrated into the optional RFR 1018 1/2 RU 19" rack frame, ideal for system installations. Ideally suited for use with the ORX 1800 receiver/OTX 1840 CWDM transmitter/OTR 1840 CWDM transceiver (all 18 wavelengths available). The OCM 1891 supports the following wavelengths: 1270,1290,1310,1330,1350,1370,1390,1410,1430nm.
