Zusammenfassung:The network includes a unidirectional multicolour loop with a main station (T) and several other stations (S1-S4). Each station includes an optical insertion/extraction frequency device (M) with frequency allocation derived as a function of the density of the traffic received by the stations. Multiple stations receive data transmitted on the same wavelength by another station and the stations share the data within that frame. Lasers (1-4) emit different wavelengths into a first optical fibre (F1) while a second fibre (F2) provides security of transmission in the opposite direction.
