ABSTRACT:
An optical fiber switching apparatus having a guide frame which is supported by an apparatus body. The guide frame has a guide groove. Disposed on the guide grooves is a movable moving member. The moving member can be moved by the apparatus along the guide groove. A slide terminal is connected by a support to the moving member. The support allows the slide terminal to approach the moving member and thereby causing the slide terminal to enter an unlocked position or to move away from the moving member and thereby causing the slide terminal to enter a locked position. The slide terminal support an end face of an optical fiber. The apparatus also includes a driving wire which has two end portions. The end portions are disposed through the moving member and are coupled to the slide terminal, thereby forming a loop in the driving wire. The apparatus can move the slide terminal by causing tension in the driving wire so as to cause the slide terminal to enter the unlocked position, and thereby allowing the moving member to-move along the guide groove by a longitudinal movement of the driving wire.
