PHOTONIC TEMPORAL MULTIPLEXER, AND PHOTONIC TIME DEMULTIPLEXER.

摘要

Provided are a multiplexer and a demultiplexer for time-multiplexing and demultiplexing binary data which is in the form of cells having a fixed number of bits. For example, to time-multiplex cells comprising 424 bits, an exemplary embodiment comprises in particular: BR/ - means (120) for multiplying by four the initial bit rate of a block of 16 bits of a cell, each cell being cut into a series of 27 blocks; BR/ - means (121) for concatenating the blocks constituting each cell after their rate has been multiplied. BR/ Similarly, a demultiplexer according to the invention comprises means for dividing the bit rate by cutting each cell into blocks, separating consecutive blocks by a free interval, then dividing the bit rate successively in each block. BR/ Application to asynchronous time division multiplexing telecommunications networks.
