For example, a plurality of multi-fiber optical fiber tapes are stacked and stored in each groove of a slot rod having a tension member in the center and a plurality of grooves formed in a spiral shape on the outer peripheral surface, and are held on the outer circumference of these tapes. It is known that a winding tape and a plastic sheath are provided in this order.

あった。In such an optical fiber cable, when an abnormal lateral pressure is applied from the outside due to a mechanical shock or the like, the optical fiber tape accommodated in the groove of the slot rod is deformed, and The microbent loss of the light transmitted through the fiber causes a local increase in the optical transmission loss. Therefore, it is very important for the maintenance and management of the cable to detect the position where such an abnormal lateral pressure is generated. However, a technique for detecting an abnormal lateral pressure has not been established yet, and it is often known that the optical fiber is broken. Moreover, it was difficult to specify the position.

きる。In the optical fiber cable of the present invention, when an abnormal lateral pressure is applied from the outside due to a mechanical shock or the like, the microcapsules containing water are broken and react with a substance that generates heat or absorbs heat by reacting with water. . As a result, the temperature of the portion locally rises or falls, and this temperature change is transmitted to the optical fiber, and the temperature of the optical fiber locally rises or falls. The temperature change of the optical fiber can be accurately detected by a distributed temperature sensor or the like to which OTDR (Optical Time Domain Reflectometry) is applied, as described later. Therefore, for example, by connecting a distributed temperature sensor to which such an OTDR is applied to an optical fiber and monitoring the temperature change, when a cable receives an abnormal lateral pressure, this can be promptly detected, and The position can be accurately specified.

ファイバの温度が局部的に上昇もしくは低下する。In the optical fiber cable constructed as described above, when an abnormal lateral pressure is applied from the outside due to a mechanical shock or the like, the microcapsules 9 containing water dispersed in the press-winding tape layer 7 at this portion are formed. The substance 8 that is destroyed and releases water, reacts with the water dispersed in the slot rod 5 to generate heat or absorb heat by the action of this water, causing heat generation or heat absorption reaction. As a result, the temperature of the slot rod 5 locally rises or falls, and this temperature change is transmitted to the optical fiber in the optical fiber tape 6, and the temperature of the optical fiber locally rises or falls.

ことができる。Therefore, although not shown, one of a large number of optical fibers is used as a sensor optical fiber, and one end thereof is a temperature measurement device capable of measuring the temperature distribution of the optical fiber, for example, a distribution obtained by applying an OTDR. If it is connected to the mold temperature sensor so that the above-mentioned temperature change can be monitored constantly or in a timely manner, it is possible to detect that the cable receives an abnormal lateral pressure together with its position. It should be noted that the distributed temperature sensor applying the OTDR used here uses the fact that the intensity of Raman scattered light generated when an optical pulse is incident from one end of the optical fiber changes depending on the temperature of the optical fiber. The temperature distribution over the entire optical fiber of several km can be measured at one time, and it is known as a highly accurate temperature measuring device. Therefore, by using such a distributed temperature sensor, it is possible to accurately detect the temperature change of the optical fiber due to the abnormal lateral pressure, and to know the position where the cable receives the abnormal lateral pressure with high accuracy over the entire length of several kilometers. it can.

Microcapsules containing calcium chloride and water using butyl rubber as a binder were attached to the surface of a polyethylene slot rod having an outer diameter of 9.4 mm in which six concave grooves were formed. Next, in each groove of this slot rod, stack three 3-fiber optical fiber tapes and store them.
A polyester non-woven fabric tape was wound around the outer circumference of these, and a polyethylene sheath was extrusion-coated on the tape, to manufacture an optical fiber cable having an outer diameter of about 15 mm. From the obtained cable, a sample cable with a length of 200 m was cut out, a distributed type temperature sensor was attached to one end of the sample cable, and an abnormal lateral pressure was applied at 100 m from the mounting end, and the temperature change of the part was examined, A temperature rise of 5-10 ° C was observed.
