Abstract
An optical multiplexing/demultiplexing device has a plurality of optical ports along a cascading optical path with wavelength-specific filters disposed at the ports. The filters are selected to form groups of at least two virtually identical filters. At least one 'add' connection is provided for admitting a selected band into the optical path, the connection being disposed at a second or consecutive (third, fourth etc . . . ) filter of the same wavelength as the band being added. The device uses a single medium for processing optical signals, e.g. a single polygonal optical block or air.
