PURPOSE: An automatic distribution system is provided to perform data communication during a terminal device failure and to improve the speed of network. CONSTITUTION: A host optical connection unit(13) is connected to a host(11) and a host connection unit(12). A first terminal unit(23) and a first terminal interface unit(22) are successively connected to a first optical terminal unit(21). A second terminal unit(33) and a second terminal interface unit(32) are successively connected to a second optical terminal unit(31). A third terminal unit(43) and a third terminal interface unit(42) are successively connected to a third optical terminal unit(41). The host optical connection unit, the first optical terminal connection unit, the second optical terminal connection unit, and the third optical terminal connection unit are formed in a ring shape by a single optical fiber. |
