Abstract

An optical-time-domain reflectometer has been constructed with a 1.55-µm Er3+:glass laser, a TeO2 acousto-optical directional coupler, and a cooled Ge P-I-N photodiode. With it, a maximum detectable fault-location length of 130 km for single-mode optical fiber has been successfully achieved at a 1.55-µ wavelength.
