DWDM multi-channel multiplexer /demultiplexer (Mux / DeMux) modules are available on ITU channel spacing of 200GHz. They demonstrate low loss, temperature insensitivity and reliable performance in any system application. Mux/DeMux modules offer low-cost wavelength management solutions that are suitable for long haul, metro, and access application.
