Tapped tee single-mode data distribution system

An eight-terminal tapped tee fiber distribution system was constructed using six single-mode fiber access couplers. Data transmission at a 500 Mbit/s rate was demonstrated with a maximum thruput loss of -27 dB. Transmission and coupling fraction data for the couplers is given as well as throughput loss measurements for the data bus. Predicted bus capacity with this type of coupler is up to 15 terminals at 500 Mbits/s with a bit error rate of 10
