OPTICAL FIBRE DEVICE, AND ITS METHOD OF ADJUSTING EMITTING DIRECTION, METHOD OF SWITCHING AND SWITCHING MECHANISM, AND METHOD OF INSPECTING OPTICAL CHARACTERISTIC AND OPTICAL CHARACTERISTIC INSPECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an optical characteristic inspection system of an optical fiber device including a switching mechanism which easily switches between the transmission and the interception of emitted light with an inexpensive and simple structure.;SOLUTION: A laser light source is connected to an incident side optical fiber of the optical fiber device and a light receiver 2 is arranged in front of a plurality of emitting side optical fibers 4c via a slit member 3. The end faces 4d of the emitting side optical fibers 4c are diagonally cut and matching oil 5 is applied selectively on the end faces 4d. When inspection light is made incident to the optical fiber device from the laser light source, the emitted light 6 from the emitting side optical fibers 4c having the end face 4d on which the matching oil 5 is applied is made incident to the light receiving face 2a of a light receiver 2 via the slit 3a. However, the emitted light 6 from the emitting side optical fibers 4c having the end face 4d on which the matching oil 5 is not applied does not pass through the slit 3a and is not made incident to the light receiving face 2a of the light receiver 2.;COPYRIGHT: (C)2008,JPO&INPIT
