The optical communication device 2 comprises a monitor 15 for monitoring a resistance welding state of the detection circuit 9 and an output control part 17 for controlling a laser diode 16. In any of cases that the optical fiber cable 4 is dropped out of the optical communication device 2, the optical fiber cable 4 is dropped out of the optical communication device 3 and the optical fiber cable 4 is burnt out, the output side swiching-on circuit 7 and the input side swiching-on circuit 8 are disconnected, thereby changing the swiching-on state that is monitored by the monitor 15. Thus, when the change of the swiching-on state is detected by the monitor 15, the output control part 17 stops emitting the laser diode 16. COPYRIGHT: (C)2005,JPO&NCIPI
