Paper Abstract
The combination of Raman amplification and optical pulse coding (OPC) is proposed to reduce the frequency
uncertainty in long-distance BOTDA under higher spatial resolution. The experimental characterization of 74.6Km
temperature sensing with measurement accuracy ~1oC under ~2.5m spatial resolution over the whole length of
sensing fiber is demonstrated. The performance comparisons of BOTDA with purely Raman amplification and
combined Raman amplification with OPC are also displayed.
