PROBLEM TO BE SOLVED: To provide an optical fiber cable switching connection system capable of a three-point opposed switching connection including a branch switching section. SOLUTION: This system is provided with first, second and third optical fiber connector switching devices for switching a first connecting point, a second connecting point and a third connecting point, respectively, in the switching connection of an active optical fiber tape coated fiber to a switching optical fiber tape coated fiber in the first connecting point within a branch switching section, and the second connecting point and the third connecting point after branching, and a switching operation is performed while synchronizing the three optical fiber connector switching devices. This system is also provided with a main synchronous switching control device and two slave synchronous switching control devices 3 for the synchronization. The timing of the operation before and after switching of the first optical fiber connector switching device is shifted from the timing of the second and third optical fiber connector switching devices, whereby the optical level fluctuation of optical signals can be suppressed. |
