A high-performance DWDM (Dense Wavelength Division Multiplexing) Mux/Demux module operating on a 200GHz channel spacing grid. Available in 4, 8, or 16 channel configurations, it enables the simultaneous transmission of multiple optical signals over a single fiber by combining (multiplexing) and separating (demultiplexing) specific ITU-standard wavelengths. Designed for scalable and efficient fiber optic networks, this passive module offers low insertion loss, high channel isolation, and excellent thermal stability, making it ideal for metro, access, and enterprise networks requiring cost-effective bandwidth expansion.
