Lynx Technik yellobrik OCM 1842 4 Channel CWDM Optical Mux/Demux (1350nm, 1370nm, 1390nm, 1410nm)

The Yellobrik OCM 1842 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. This flexibility makes the OCM 1842 ideal for efficiently managing multiple optical signals in broadcast and professional video applications.

Key Features

• Transmits and receives up to 4 channels over a single fiber link
• Passive operation requiring no power
• Expandable to 16 channels by combining up to four modules via the UPG port
• LC/PC single-mode optical connections for reliable performance
• Optional ½ RU 19” rack frame (RFR 1018) for organized module integration
