    摘要： Disclosed is an optical communication system in which a digital data bus constituted by optical fiber is used as a transmission line. Each terminal equipment (A, B, ..., D) measures an optical output level to enable the terminal equipment to receive a packet transmitted from the terminal equipment per se and informs other terminal equipments of the measured optical output level. Each terminal equipment establishes its optical output level to be the largest one of the levels informed thereto. Further, each terminal equipment measures the delay time of an acknowledge bit transmitted from the other terminal equipments to thereby shift the sampling point by the mean value of the measured delay time, so that bus connection of terminal equipments through optical fiber can be facilitated, channel access control based on CSMA/CD can be performed, and wiring between the terminal equipments can be saved by performing multiple transmission of audio signals and video signals as well as digital data.
