The OCM 1841, OCM 1842, OCM 1843, OCM 1844 are compact CWDM passive 4 channel optical multiplexers / demultiplexers designed to send and receive up to 4 individual signals over a single fiber link. Each module has an UPG (Upgrade) port to cascade into the other 4 channel modules, expanding the capability of the system to a maximum of 16 channels.
The modules can be used standalone or integrated into the optional RFR 1018 1/2 RU 19" rack frame, which can accommodate all four modules. Ideal for system installations. Ideally suited for use with the CWDM yellobrik fiber modules (all 16 wavelengths are available).
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 (18 wavelengths available as specified in ITU-T G.694.2)
