Title: Pulse tester for optical cable
Inventor: TOKUDA MASAMITSU
IPC: G01M11/00
Filed: 1981-03-31
Abstract: PURPOSE:To enable avoidance of saturation of an amplifier and restraint of drift by impressing a blanking pulse on a multiplier phototube transducing a pulsed light emitted from an optical cable into an electric signal to control the multiplication and by applying digital processing to the output of the tube. CONSTITUTION:A light pulse from a pulsed light source 1 of a tester 20 falls on an optical cable 4 to be tested via an optical connector 3 and is reflected by the cable 4 and emitted via the connector 3. Then, it is separated by a directional coupler 2, received by a multiplier phototube 6 of a photoelectric transducing element and transduced into an electric signal. A blanking pulse from a pulse gennerator 7 is impressed on the electrode of the multiplier phototube 6 to control multiplication of the light, whereby the saturation of amplification caused by an intense reflected light based on Fresnel reflection is avoided. Thus, a wide dynamic range processing ranging from a minute Rayleigh-scattering reflection light to an intense Fresnel reflection light is conducted excellently. Moreover, the output of the multiplier phototube is subjected to digital processing in an A/D converter 11, an averaging circuit 12 and a zero-level detection circuit 14 so as for the drift to be restrained, and thus a pulse test can be performed with high precision.
