200GHz Cassette-Type Dense Wavelength Division Multiplexer
Pictures and Schematic Diagram
The 200GHz cassette type dense wavelength division multiplexer is the result of years of telecommunication experiences in thin-film flitter technology. Individual components are available on ITU channel spacing of either 200GHz or 100GHz. This range of fiber optic components exceeds the requirements of Telcordia GR-1221. The 200GHz fiber optic multiplexer demonstrate low insertion loss and temperature insensitivity, and reliable performance in varieties of system applications.
