摘要： PROBLEM TO BE SOLVED: To provide a ring type optical communication system which keeps data transmission even when an abnormality occurs in one of optical transmission lines forming a network. SOLUTION: One of nodes 2a-2d is adopted as a master station and the others are slave stations. When the abnormality occurs in one of the optical transmission lines 3a-3d connecting the nodes 2a-2d, bi-directional data transmission is performed between the master station and the slave stations through the use of a route at the opposite side of the optical transmission line with the abnormality, which connects the nodes being the both ends of the optical transmission line with the abnormality. Thus, correspondence is conducted with respect to a case when the abnormality occurs in the optical transmission line without using a restoration communication line.

摘要： PROBLEM TO BE SOLVED: To provide an optical multiplex transmission system that is simplified without the provision of a start signal electric wire other than a data transmission line and which starts each control node. SOLUTION: A light receiving section 11 of each control node which connects to an optical multiplex transmission line is operated by the application of power from a power supply 14 and receives an optical signal from other control node. A mode switching section 23 alternately selects a multiplex communication mode or a sleep mode for each prescribed time. A light receiving section power supply control section 24 and a 1st switch 15 generate a power supply signal, where the duty factor of a power supply time nearly corresponding to the multiplex communication mode and a power supply non-application time nearly corresponding to the sleep mode is preset and supply the signal to the light receiving section. When multiplex communication mode is selected and an optical signal is received, a mode changeover section continues the multiplex communication mode during the reception of the optical signal and the light receiving section power supply control section continuous the supply of power by a power supply signal to the light receiving section.
