Abstract

The signal-to-noise ratios of single-pulse and coded Raman optical time-domain reflectometry (ROTDR) are analytically modelled. It turns out that there is an upper limit of coding gain of ~9 dB imposed by amplified shot noise in coded ROTDR.

编码拉曼光时域反射计的编码增益分析

对单脉冲和编码拉曼光时域反射计(ROTDR)的信噪比进行了解析建模。结果表明，在编码的ROTDR中，受放大的散粒噪声影响，编码增益的上限为~ 9db。
