Abstract
We have observed Rayleigh backscatter in a single-mode fibre in optical time domain refiectometry at 1.56 μm wavelength to a range of 100 km using a D2 gas-in-glass laser, and to 60 km at 1.53 μm using an injection laser. The low-noise receiver used an InGaAs PIN photodiode and a FET-input operational amplifier with averaging of 1000 times to provide signal/noise enhancement.
