Abstract
A high-performance single-mode optical time-domain reflector (OTDR) incorporating a new low-noise receiver design utilising a PIN diode detector and a transimpedance amplifier is described. With a 1.3 μm laser diode source a dynamic range of 30 dB one way is achieved, and using an Nd: YAG laser source the dynamic range is 41 dB one way.Keywords
