We present a comprehensive solution for in-line and realtime monitoring of long distance pipeline using distributed fiber optic sensors. The technique is based on Brillouin scattering and is capable of measuring strain and temperature over distances larger than 150 km with meter resolution using a single instrument. The solution includes ground movement, leakage and third party intrusion detection. The solution presentation is supported by experimental results and practical cases of implementation.
