Single Directional CWDM MUX/DEMUX Module

Auxora's Coarse Wavelength Division Multiplexer (CWDM) module demonstrates low loss and reliable performance.  The module features broad passband and high isolation, making it ideal for functioning with inexpensive, uncooled lasers. The device features up to 4 or 8/16/18 low dispersion channels, thereby enabling it to be a high capacity, low cost product for CATV and metro/access network applications. Easily customizable, Auxora’s CWDM module can be configured from a standard list of packaging and connector options.
