Abstract
A bilateral optical transmission system for pulse information disclosed which can accommodate variations in the relationship between the down-link signal transmission rate and the up-link one. A single bilateral optical transmission line is laid between first and second positions. A transmission pulse train with pulse transmission time slots set therein at fixed time intervals is provided onto the transmission line from the first position. A return pulse train is retransmitted from the second position to the first position over the bilateral optical transmission line. The return pulse train is obtained by gating the transmission pulse train with up-link information pulses from the second position to the first position in synchronization with up-link pulse transmission time slots for the transmission of the up-link information pulses so that at least one predetermined transmission time slot in each unit transmission period defined by a predetermined number of pulse periods in the transmission pulse train is used as the up-link pulse transmission time slot. At the first position, at least one time slot other than the up-link pulse transmission time slot in each unit transmission peri…
