| Abstract: | The ability of the two-point technique to obtain accurate backscatter loss signatures for fibre systems with long repeater spacing is investigated. A systematic analysis of the attenuation range capability of two-point processing is presented and a predicted measurement range of 40 dB one-way fibre attenuation verified by measurement. The analysis takes into account the effect of receiver bandwidth, quantization noise and A–D converter nonlinearity. |
