摘要：

A distributed temperature sensor for transient threshold monitoring with a 22 km sensing length, based on the Brillouin loss in standard communications fibre, is demonstrated. The system can be used for real-time monitoring of a preset temperature threshold. Good S/N ratios were achieved with only 8-16 sample averages giving a response time of 2 to 4 s with a temperature uncertainty of +/-1 degrees C.
