An eight-terminal fiber optics data bus using tee couplers

Tapped tee single-mode data distribution system

“…The problem of minimizing the link throughput loss when the coupling fraction K is allowed to vary along the link length has been solved by Altman and Taylor [4] and by Auracher and Witte [ 121. Again, restricting K < 1 they arrive at a symmetrical distribution in which K decreases, from K = 1 at the first coupler, towards the link midpoint (n is restricted to be even) and then increases in a symmetrical fashion towards the Six single-mode fused access couplers were fabricated from ITT single-mode fiber with a measured V number of 2.08 at h = 0.82 pm and a 5.2 pm core diameter.…”

“…System design has centered on two basic coupler components: the "star" coupler 133 and the access "tee" coupler [ 11. To date, several demonstration systems have been constructed and tested [4]- [5].…”
