Abstract:
A reflection mirror optical fiber switch comprising:a first collimator lens assembly (C1) having a pair of optical fibers (F1) and (F2) disposed symmetrically with respect to an optical axis of a lens; a second collimator lens assembly (C2) having a pair of optical fibers (F3) and (F4) disposed symmetrically with respect to an optical axis of a lens; an aligning block (B) in which the first and second collimator lens assemblies are opposed each other with their optical axes aligned, and supported so that the optical fiber (F1) and the optical fiber (F4) are optically coupled and the optical fiber (F2) and the optical fiber (F3) are optically coupled; a reflection mirror assembly formed by a reflection mirror shaft rotatably installed in a shaft hole provided in parallel to an optical axis of the lens in the aligning block, a reflection mirror provided on the reflection mirror shaft so that the reflection mirror can move between a first position where the reflection mirror reflects light from the optical fibers to focal surfaces of the lenses at right angles to the optical axes of the lenses and a second position where the reflection mirror causes the light from the optical fibers to directly enter the focal surfaces of the lenses, and defining means for defining a position of the reflection mirror at the first position by using the aligning block as a reference; and driving means for driving the reflection mirror.
