PCT No. PCT/GB86/00127 Sec. 371 Date Dec. 11, 1986 Sec. 102(e) Date Dec. 11, 1986 PCT Filed Mar. 6, 1986 PCT Pub. No. WO86/05342 PCT Pub. Date Sep. 12, 1986.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 and sampling devices such as optical modulators which are controlled at the Bit Rate so that the output signals of the optical modulators correspond to respective ones of the four channels of the original multiplexed signal. These demultiplexed signals may then be converted by regenerators into corresponding electrical signals.
