LynxTechnik yellobrik 4 Channel Fibre CWDM - LC Connectors

Product Code LYOCM1842
Manufacturer LynxTechnik

Request more information or contact us now for purchasing information.


The OCM 1842 is a compact CWDM passive 4 channel optical multiplexer / demultiplexer designed to send and receive up to 4 individual signals over a single fibre link. The module has an UPG (Upgrade) port to cascade into other optical multiplexer / demultiplexer to expand the total number of multiplexed signals.

The module can be used standalone or integrated into the optional RFR 1018 1/2 RU 19" rack frame, which can accommodate up to four 4 channel modules. Ideal for system installations. Ideally suited for use with the CWDM yellobrik fibre modules.

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).
