Analyzing the coding gain of coded Raman optical time-domain reflectometry
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.
