Abstract:
In a wavelength division multiplexed network, a method for removing and inserting information in a wavelength division multiplexed signal having a plurality of optical channels, the method comprising the steps of:transporting information in a parallel bus transmission group within the wavelength division multiplexed signal, the parallel bus transmission group including a predetermined number of the plurality of optical channels for carrying multiplexed information supplied by a source in a parallel format, wherein the information is formatted as bytes, each byte having N bits, the transporting step further characterized by byte-wide parallel transmission wherein each optical channel in the parallel bus transmission group carries a corresponding one of the N bits of a byte being transmitted: at a node in the network, selectively removing byte-wide parallel-formatted information carried in the parallel bus transmission group; and inserting byte-wide parallel-formatted information supplied at the node into the parallel bus transmission group for transmission in the wavelength division multiplexed signal.
