The CWDM Mux/Demux 4/8/16ch is a compact and efficient passive optical module designed for coarse wavelength division multiplexing (CWDM) applications. It enables the simultaneous transmission of 4, 8, or 16 wavelengths over a single fiber by combining (multiplexing) multiple optical signals at different ITU-standard CWDM wavelengths (ranging from 1270nm to 1610nm) onto one fiber, and separating (demultiplexing) them at the receiving end. Ideal for expanding fiber capacity in cost-sensitive access and enterprise networks, this solution offers low insertion loss, high channel isolation, and excellent thermal stability. With scalable configurations and a rugged, space-saving design, the 4/8/16-channel CWDM Mux/Demux provides a reliable, plug-and-play solution for efficient bandwidth utilization in metro networks, fiber-to-the-x (FTTx), and data center interconnects.
