Abstract

All modern optical time-domain reflectometers (OTDR) are digital. A peculiarity of a backscatter signal in fiber-optic networks is a wide dynamic range that leads to high demands of a number of digit ADC. Moreover, ADC should be of high speed and low nonlinearity. In this paper we discuss specificity of working ADC in OTDR and the effect of ADC parameters on OTDR features.
