<p>A method and system for demultiplexing an optical signal having a bit rate in the order of GBit/second. The system comprising optical demultiplexing means including delay units (8-10) and sampling devices such as optical modulators (4-7) which are controlled at the bit rate (B) so that the output signals from the optical modulators (4-7) correspond to respective ones of the four channels of the original multiplexed signal. These demultiplexed signals may then be converted by regenerators (11-14) into corresponding electrical signals.</p> |
