Dense wavelength-division multiplexer
Dense wavelength-division multiplexer
This dwdm is an 8- or 16-channel module for dense wdm applications. Its narrowly spaced itu wavelengths can be spaced 200 GHz apart or less while maintaining low insertion loss and high adjacent channel isolation. A low pdl ٞ.1 dB is guaranteed, according to the manufacturer. The dwdm uses thin-film interference filters to separate or multiplex optical transmission signals. The optical path is epoxy-free.
