To measure strain, temperature and loss distributions along optical fibers, recently, we developed a new structural health monitoring technique, named slope-assisted Brillouin optical correlation-domain reflectometry (SA-BOCDR). Although its fundamental operational principles have been well investigated with some unique features, distributed measurement using a kilometer-order sensing fiber has not been reported yet. In this work, we demonstrate SA-BOCDR-based long-range distributed temperature measurement using 13-km-long sensing fiber. After showing that a length of a delay fiber should be at least four times longer than that of the sensing fiber, we detect a 3-m-long heated section around 11 km apart from a circulator. |
