ABSTRACT:
A fiber optic local area network including a plurality of passive star couplers each capable of connecting to a plurality of users. One connection input to and output from each passive star coupler is connected to a respective output and input of an active star coupler. The active star coupler stores the round-trip transmission times to each passive star coupler and upon receipt of a signal from a passive star coupler inhibits output to that passive star coupler for the signal duration and inhibits input from all other passive star couplers for the signal duration plus the round-trip transmission delay.
