Transition Networks has announced the introduction of its new Course Wavelength Division Multiplexing (CWDM) solution. Transition’s passive optical CWDM devices utilize thin-film filter technology and are available in various wavelength combinations based on the entire wavelength spectrum (1270nm – 1610nm in 20nm increments) defined by the ITU G.694.2 CWDM standard. These CWDM devices are available in two main configurations: Multiplexer/Demultiplexer (Mux/Demux) modules and Optical Add/Drop Multiplexer (OADM) modules.
