Abstract
A contention-type data communication system such as an optical star-configured network comprises a plurality of stations connected with one another through data bus. To detect a signal collision quickly, each of the stations is arranged to transmit a collision-detecting packet which has a predetermined time length T.sub.1 and a predetermined pulse pattern, and then transmit a data packet after a time interval T.sub.2. The number or pattern of pulses received during a time period T.sub.1 +T.sub.2 from the start of reception of a collision-detecting packet is compared with that of the self-transmitted collision-detecting packet so that the signal collision is detected when noncoincidence occurs.
