The invention belongs to the related field of
optical communication transmission technology, and discloses a light
flame-retardant sensing optical cable capable of fast positioning, the sensing optical cable comprises a sensing
optical fiber, a waterproof layer, a reinforcing element and a
flame-retardant layer from inside to outside, the side surface of the sensing optical cable is provided with a self-
adhesive layer, the sensing
optical fiber is used for performing real-time sensing on external disturbance, and the
flame-retardant layer is provided with a self-
adhesive layer. The waterproof layer is arranged on the periphery of the sensing
optical fiber and plays a waterproof role, the reinforcing element is used for improving the mechanical performance of the whole sensing optical cable, the flame-retardant layer is arranged on the outermost layer of the sensing optical cable and plays a flame-retardant role, and the self-
adhesive layer is used for attaching the sensing optical cable to a target object. According to the sensing optical cable, it is ensured that the sensing optical cable can be installed in a non-underground laying mode in an efficient, reliable and convenient-to-
control mode, the sensing optical cable has the advantages of being high in positioning precision, light, good in flame retardance and the like, meanwhile, the later maintenance work is greatly facilitated, and therefore the sensing optical cable is especially suitable for application occasions such as accident positioning of expressways and elevated roads.
