Optical continuity testing transmitter

Apparatus for receiving an optical test signal, from a transmitter pulsating at a selected repetition rate, comprising, a portable voltage source, a PIN diode for sampling the test signal and generating a voltage pulsating at said repetition rate and with an amplitude proportionate to the amplitude of the sampled test signal, an indicator for indicating the amplitude of the sampled test signal, amplifying means connected between the indicator and the PIN diode, a filter circuit between the PIN diode and the amplifying means for reacting to the transitions in amplitude of said voltage from the PIN diode.

Optical fiber continuity testing with pulsating optical test signal

A receiver for receiving an optical test signal from an optical transmitter pulsating at a selected repetition rate is disclosed. The receiver comprises an optical detector for sampling the test signal and generating a voltage signal pulsating at the repetition rate and with an amplitude proportional to the amplitude of the sampled test signal. The receiver also includes an indicator for indicating the amplitude of the test signal relative to the amplitude of a calibration signal.
