摘要：

A reflectometry system having a high spatial resolution and an elongated measurement range is constructed, considering an application to optical subscriber networks, using a technique of synthesis of optical coherence function (SOCF). In this system, parameters have been adjusted so that the measurement range is elongated by successively shifting the 20 m measurement window while keeping a high spatial resolution. Reflectivity distribution around the end of a 5 km test fibre is successfully measured with a spatial resolution of 11 cm and an elongated measurement range of 1 km.
