ROADM & Add/Drop Modules Fixed OADMs for Metro Access
The COADM Series of Configurable Optical Add Drop Multiplexers selectively adds and drops individual or a set of wavelength channels from a DWDM multi-channel stream.
Furthermore, this sub-assembly serves as a node to interchange wavelength channels among fiber routes. The COADM uses established JDSU products as building blocks, e.g. DWDM mux/demux, and voltage controlled attenuators. Both opto-mechanical and solid state switch versions are offered.
The COADM can be easily customized to meet customer requirements, such as number of channels, filter specifications and power equalization.
The COADM sub-assembly is compact and directly mountable on a printed circuit board.
