摘要： PURPOSE:To hold the mirror surface-like cut surface of a core with a plug without damaging the cut surface by rotating a rotary mechanism for holding a knife part and a thin plate part with an interval eccentrically from the center axis of a coupler. CONSTITUTION:An optical fiber core 1 exposing its strand part 2 is penetrated into a ferule part 11 of a simple type optical connector plug and fixed and the rotary disc 51 of which annular projection 52 is engaged with a groove 26 is rotated around an axis L2 by 180 deg.. Since the axis L2 is eccentric from the center axis L1, the flexible thin plate 40 and the knife part 30 are moved immediately under the strand 2 and immediately over the strand 2 respectively, the strand 2 is initially cut by the knife part 30 and then the strand 2 is bent together with the thin plate 40 to obtain a cut surface approximate to a mirror surface. Consequently, it is unnecessary to penetrate the cut strand into the ferule part and a cut surface approximate to a mirror surface can be always secured for the plug without damaging the cut surface.

CONSTITUTION:A composing circuit 15 modulates the about 270Hz output of a rectangular wave oscillator 11 with the about 1Hz output of an extremely low frequency oscillator 14 and outputs an about 270Hz signal at intervals of one second. A light emitting element driving circuit 12 drives a light emitting element 13 with the output signal of the circuit 15. Consequently, the element 13 transmits the test signal modulated with the about 270Hz signal at intervals of one second.

At this time, the buzzers 24 and indicating instrument 25 operate intermittently at specific intervals of, for example, one second to discriminate the fiber 2 to be detected easily and correctly with a signal with a specific interval different from noises.

摘要： PURPOSE:To detect radiation power effectively by dividing the curved part of an optical fiber into two stages, radiating light from inside a core part to a cover body at the 1st curved part, and arranging a photodetector at the 2nd curved part. CONSTITUTION:The optical fiber 1 has the 1st and the 2nd curved parts 5 and 6 at middle parts and the photodetector 4 is arranged outside the 2nd curved part 6. Popagating light 2a incident from the incidence end of the optical fiber 1 is radiated partially from the core part 1a at the 1st curved part 5 and converted to a mode wherein the light propagates in the cover body 1c. The light 2d propagating in the cover body 2 is emitted from the cover body 1c to the outside space at the 2nd curved part 6 by the curvature. Further, a part of light 2a propagating in the core part 1a is radiated externally at the 2nd curved part 6 and added to the light radiated from the curved part 6. Thus, the radiation power is detected efficiently.
