Abstract :
A highly sensitive collision detection technique that can recognise collision of optical signals with an 8 dB optical power difference is described. The maximum bit time needed to determine such a collision is calculated to be 700 bits for an 8 dB difference. This value has been verified experimentally in a passive optical star system with 100 stations.
