BiDi CWDM Passive Optical Multiplexers
Single fiber CWDM solutions for bidirectional wavelength multiplexing. Maximize fiber capacity with passive Mux/Demux, OADM, and Line Termination units for metro and access networks.
Single Fiber (BiDi) CWDM multiplexers enable up to 9 independent data channels over a single fiber strand using bidirectional wavelength separation. Based on ITU-T G.694.2 with 18 CWDM wavelengths (1271-1611nm), these passive devices require no power or cooling, offer 100+ year MTBF, and support any protocol including 1G/10G Ethernet, SDH/SONET, and Fibre Channel. Our product line is designed for minimal insertion loss and modular growth—start with 2-4 channels and expand to full capacity as your network demands increase.

Full Capacity Mux/Demux
Maximum channel density single fiber CWDM multiplexers supporting 8-9 data channels (16-18 wavelengths) over one fiber strand.
