Abstract
PURPOSE: To accomplish the measurements at the indidence side by providing a terminal processor which has a highly reflective terminal device at the emanating side and a three-dimentional position adjusting jig at the incidence side.
CONSTITUTION: The incidence end of an optical fiber 1 is dipped in a regulating liquid 2-3 having the same refractive index as the core material in a holder body 2-1, the position of which is adjusted by the three-dimentional position adjusting device 3 of a terminal processor 2, so that it abuts against a transparent member 2-2 made of the same material as the core material which is formed with a nonreflective coating 2-4. On the other hand, the emanating end of the fiber 1 is dipped in the regulating liquid similar to the adjusting device 3 and abuts against the reflective film having highly reflective characteristics for the waveforms of a light source so that the incident light to be measured having a sufficiently small core diameter from a light source 4 and an incidence optical system 5 is reflected at the terminal device 3 at the emanating side so that it passes back and forth in the optical fiber 1. As a result, if the photoelectricities of the incidence light and its reflected light are detected by optical detectors 6 and 7 which are connected at a low connection loss with the optical system 5, the loss measurement can be accomplished at the incidence end to require no communication with the emanating end so that the measurement can be accomplished easily and reliabliy in site
