Lynx Technik yellobrik OCM 1844 4 Channel CWDM Optical Mux/Demux (1550nm, 1570nm, 1590nm, 1610nm)

The OCM 1844 is a compact CWDM passive 4-channel optical multiplexer/demultiplexer designed to facilitate the transmission and reception of up to four individual signals over a single fiber link. Operating on wavelengths 1550nm, 1570nm, 1590nm, and 1610nm, this module includes an Upgrade (UPG) port that allows cascading with other 4-channel modules, enabling system expansion up to a maximum of 16 channels. The OCM 1844 can function as a standalone unit or be integrated into the optional RFR 1018 1/2 RU 19” rack frame, which can accommodate all four modules, making it ideal for system installations. This module is particularly well-suited for use with CWDM yellobrik fiber modules, as all 16 wavelengths are available. :contentReference[oaicite:5]{index=5}
