Abstract :
A single-mode optical time-domain reflectometer (OTDR) operating at a wavelength of 1.3 ¿m with a dynamic range in excess of 26 dB one way is reported. The equipment incorporates a semiconductor laser source and a new low-noise optical receiver design utilising a PIN diode detector and a transimpedance amplifier.
