ABSTRACT:
A system and method for providing wavelength division multiplexer is disclosed. The wavelength division multiplexer is for separating an optical signal into a plurality of components. The wavelength division multiplexer includes a splitter and a plurality of isolators coupled to the splitter. The splitter is for separating the optical signal into a plurality of groups. Each group contains a portion of the plurality of components. The plurality of isolators correspond to the plurality of groups. Each of the plurality of isolators is for isolating each component of the corresponding group. In one embodiment, the splitter further includes a splitter input. In this embodiment, the wavelength division multiplexer further includes a filter coupled to the splitter input. The filter is for isolating one of the plurality of components.
