求められている。2. Description of the Related Art Conventionally, in the case of communication cables and power cables, if water intrudes into the interior, the infiltrated water runs axially to deteriorate the electrical and transmission characteristics of the cable. It has been known. Therefore, there is a demand for the development of a technique that can detect such an inundation early and reliably.

という原理を利用したものである。As a technique of this kind, for example, there is known a water infiltration detection sensor in which an optical fiber and an absorbing / expanding member for absorbing and expanding infiltrated water are combined. This is based on the principle that the absorption expansion member expands in the presence of water and stress is generated to deform the optical fiber, resulting in an increase in transmission loss.

In that case, there is a problem that the accuracy is lowered.

し得る新しい技術として注目されている。Under such circumstances, recently, a substance that reacts with water to generate heat or absorbs heat is placed in the vicinity of the optical fiber, and in the event of water immersion, the substance may react with water to generate heat or absorb heat. Since it causes a temperature change, this is OTD
A distributed thermometer applying R, that is, a temperature measuring device that utilizes the fact that the intensity of Raman scattered light generated when an optical pulse is incident from one end of an optical fiber changes depending on the temperature of the optical fiber A technology for detecting water has been developed, and it is attracting attention as a new technology that can establish a highly reliable inundation detection system.

困難になる。In the present invention, as described above, the coating layer containing such an exothermic or endothermic substance is made into a foam, or a cellulosic fiber is contained together with the exothermic or endothermic substance, or the coating is applied. A water-soluble resin is used as the base resin forming the layer. Further, it may be a foam and may contain cellulosic fibers. As a result, the diffusion speed of water in the coating layer increases, and as a result, highly reliable detection of water infiltration becomes possible. That is, in the event that water is submerged, if the coating layer is, for example, a foam, the submerged water will rapidly diffuse in the coating layer, and the exothermic or endothermic reaction between water and the exothermic or endothermic substance will proceed rapidly, It causes a noticeable temperature change. Therefore, it is possible to detect the occurrence of flooding and the position thereof at an early stage and with high accuracy. By the way, if the diffusion of water is slow, even if heat is generated or absorbed, it is immediately absorbed by the surroundings and does not appear as a sufficient temperature change, making it difficult to detect water immersion.

That is, for example, even if the foaming ratio is less than 40%, a good effect can be obtained when the cellulosic fiber is blended. Examples of the water-soluble resin include water-soluble urea resin, polyvinyl alcohol resin, methyl cellulose resin, polyethylene oxide resin, starch resin, hydroxypropyl cellulos resin, casein and the like.

おそれがある。In the present invention, the coating layer containing these exothermic or endothermic substances may be directly provided on the optical fiber, or other protective coating layer such as silicone resin or ultraviolet curable resin. It may be provided via. Further, a protective coating layer may be provided on the outer periphery of the coating layer containing a heat generating or endothermic substance. In particular, in the case of a coating layer that uses a water-soluble resin as a base resin, in order to facilitate storage and handling, the coating layer containing a heat-generating or endothermic substance is applied to the outer periphery of a water-insoluble resin of about 5 to 20 μm. It is desirable to coat the protective layer with a small thickness. The thickness of the coating layer containing the exothermic or endothermic substance is preferably 0.2 mm or more. If the coating thickness is too thin, the absolute content of heat-generating or endothermic substances will be small, and the temperature change will be small and the detection accuracy may be reduced.

に伴う事故の発生を未然に防止することができる。In the water intrusion detection line of the present invention, when water is infiltrated, the water infiltrated at that portion rapidly diffuses and penetrates into the coating layer containing the exothermic or endothermic substance.
Due to the reaction between water and an exothermic or endothermic substance, the ambient temperature rises or falls remarkably. Therefore, if the temperature change is detected by a distributed thermometer to which the OTDR is applied via the optical fiber, the occurrence of water immersion and its position can be detected with high accuracy. In addition, in the cable of the present invention using this, since the above-described inundation detection line excellent in inundation detection accuracy is provided inside, in the unlikely event that there is inundation, the inundation position can be set early. Moreover, it is possible to detect with high accuracy, and it is possible to prevent the deterioration of the cable and the occurrence of an accident accompanying it.
