Abstract

PURPOSE:To couple the optical station by means of an optical data way, by measuring the optical branch device having a function for coupling an output signal from the optical station to the optical fiber, and arranging it at the position which is to be controlled. CONSTITUTION:An optical signal reaches the optical station 1 through the optical fiber 1n, the optical branch path 21a of the optical branch device 21, and the branch optical fiber 1a. The output of the optical station 1 reaches the optical station 2 through the branch optical fiber 1b, the optical coupling path 21b of the optical branch device 21, the optical fiber 11, the optical branch path 22a of the optical branch device 22, and the optical fiber 2a. The output of the optical station 2 reaches the next optical station connected to the optical branch device through the branch optical fiber 2b, the optical coupling path 22b of the optical branch device 22, the optical fiber 12, the optical by-pass path 23c of the optical branch device 23, and the optical fiber 13. In case of the branch device to which the optical station is not connected, the control signal is turned off.
