英文摘要	Abstract of the Disclosure Disclosed are optical data bus configurations for interconnecting terminals so that any terminal can communicate with any other terminals. It is known to do this by connecting terminals serially using two trunk optical fibers and to connect terminals together in a star configuration using a single transmission star or reflection star. The serial network is limited by optical loss while the star network requires more optical fiber and is more costly. Disclosed is a serial bus which uses six fibers arranged in two groups of 3 each, the groups conducting light in mutually opposite directions. A transmitting means in each terminal is coupled to two of the fibers in each group and terminals adjacent any one terminal are connected to a different two fibers than the one terminal. Another arrangement disclosed uses hybrid reflection transmission star couplers. Terminals can be connected to reflection ports of the hybrid couplers, while the couplers can be interconnected by the transmission ports thereof. A relatively small number of fibers are required to interconnect a large number of terminals.
