<p>Optical communication network comprising several stations (S1, S2, S3, S4) each including a data transmitter (E1, E2, E3, E4) and a data receiver (R1, R2, R3, R4), the stations being interconnected by optical signal transmission supports (22, 24) and means (26) of managing the network, each station comprising, at transmitter level, means of encoding the data (10, 12, 14) by modulating an optical delay, a modulated optical delay including a fixed main delay and a variable modulating delay which is small compared to the fixed main delay, and at receiver level means of decoding the data (16, 18, 20) by demodulating an optical delay. Application to private communication networks. <IMAGE></p> |
