Pictures and Schematic Diagram

Housed in a tough cassette, this dense wavelength division multiplexer is the result of years of telecommunications experience in thin-film filter technology. Its channel spacing is either 200GHz or 100GHz depending on the model you’ve chosen. All DWDM models have been built to standards exceeding Telcordia GR-1221. The same as our other styles of optical multiplexers, they offer low insertion loss, high reliability, and outstanding thermal stability.
