Apparatus and method for interconnection for fabrication of combinatorial transmissive star couplers suitable for single-mode fiber optic local area networks. Various types of couplers including evanescent wave couplers are utilized to synthesize artibrarily large fiber optics star couplers free of multi-path interference providing high quality single-mode capability.

Transmissive single-mode fiber optics star network

An optimized fifteen-terminal tapped-tee data bus and a 9 × 9 star data bus were constructed using low-loss single-mode fiber fused-tapered 2 × 2 and 3 × 3 couplers. High-speed data transmission was demonstrated at 500 Mbit/s with a maximum throughput loss of 33 dB for the tapped tee system and mean throughput loss of 11 dB for the star system. System design parameters and experimental results are given in each case.

Fiber Optics in Adverse Environments

A fiber optic data bus topology is introduced which avoids both the "central failure point" problem that afflicts single star topologies and the intermessage dynamic range problem evident in systems using directional couplers.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
