CWDM Band Splitter

Auxora's CWDM band splitters are based on thin film filter platform, they are used to conveniently split ITU channel spacing of 20nm into manageable channel bands. These highly reliable components demonstrate low loss, good thermal insensitivity, and reliable performance. They are designed to meet the requirements of Telcordia GR-1221-CORE. Used with MUX/DEMUX and add/drop applications, these band splitters can manage multiple ITU channels.
