Abstract
A switch device with a spiral mechanism for optical fiber is disclosed for improved reliablility. It includes: (a) a plurality of non-rotatable optical fibers, each having first end and second ends, the first end of each the non-rotatable optical fiber being provided with a parallel convergent lens, the second end of each the non-rotatable optical fiber being provided with a connector to connect an interface for receiving an optical signal; the plurality of the non-rotatable optical fibers being fixed on a circular fixture; (b) a rotatable optical fiber having first and second ends, wherein the first end of the rotatable optical fiber passes through a fixture hole, and connected with connector for receiving a optical signal, while the second end of the rotatable optical fiber being fixed to a motor; and (c) a spiral pipe made of a rigid material being sleeved on a portion of the rotatable optical fiber between the first and second ends The second end of the rotatable optical fiber is arranged such that it can be connected to the first end of one of the non-rotatable optical fibers without contact to form into a coupling channel within an angular scope of 360 degrees.
