Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To improve the optical capacity and the workability, to reduce the cost, and to cope with the increase of signal light by making characteristics of a coupling part efficient and reducing the number of parts with a structure where a mirror is moved to and removed from the position, where it intercepts the optical path between collimator lenses, to switch the optical path of signal light. SOLUTION: Optical fibers 1 are fixed to two-core ferrules 2, and terminals of optical fibers are arranged so as to face each other, and collimator lenses 3 are arranged between them. In this confocal optical system, a mirror 4 which reflects signal is moved to and removed from the position, where it intercepts the optical path between collimator lenses 3, to switch an output port. At the time of power-on, signal light passes the collimator lens 3 and converges on the output port in the counter position because the mirror 4 opens the optical path. At the time of power-off, signal light passes the collimator lens 3 and is reflected by the mirror 4 and passes the same collimator lens 3 again and converges on an optical fiber for output in the same ferrule as the input optical fiber because the mirror 4 intercepts the optical path to reflect the light.
