Lynx Technik yellobrik OCM 1841 4 Channel CWDM Optical Mux/Demux (1270nm, 1290nm, 1310nm, 1330nm)

The OCM 1841 is a compact CWDM passive 4-channel optical multiplexer/demultiplexer designed to transmit and receive up to four individual signals over a single fiber link. Each module features an Upgrade (UPG) port, allowing cascading with other 4-channel modules to expand the system's capacity to a maximum of 16 channels. The modules can function as standalone units or be integrated into the optional RFR 1018 1/2 RU 19” rack frame, which can accommodate all four modules, making them ideal for system installations. They are particularly well-suited for use with CWDM yellobrik fiber modules, covering all 16 wavelengths.
