| Abstract: | We present an analysis of the anti-Stokes in Raman backscatter for fiber temperature sensors to quantify the effect of varying the gain of the avalanche photodiode. An optimal gain was found based on maximising the SNR of the received circuit output. |

| Keywords: | avalanche photodiode optic-fiber sensor signal to noise ratio |
