CWDM multiplexer and demultiplexer modules are based on free-space cascaded thin-film filters integrated on an optical bench with high temperature stability. The modules are entirely passive. The filter insertion loss profiles feature flat top and steep slopes. The thin-film filters achieve high center frequency stability over the entire operating temperature range.
- Low insertion loss
- Wide and flat pass band
- High adjacent channel isolation
- CWDM transmission
- Telecom and CATV networks
