DWDM multiplexer and demultiplexer modules combine a cascaded set of thin-film filters each housed in a 3-port cylindrical package. 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
