... The HWM 1100A series of DWDM optical passives are used to implement Harmonic's DWDM solutions. Due to their exceptional flatness and performance, these multiplexers can be used to either multiplex or demultiplex a set of wavelengths on the ITU Grid. This allows the operator to reduce the number of s ...
