摘要： PURPOSE:To prevent the bending and microbending of an optical fiber in a cable core consisting of numbers of optical fibers due to external force by covering the cable core with a layer of a viscous material having specific mixing consistency to an at least 1mm. thickness. CONSTITUTION:The cable core 1 is constituted by forming an optical fiber unit 11 of six optical fibers stranded around a tension member and then stranding eight units around another tension member 12, e.g. rubber or plastic insulated power cable. The layer 2 of the visous material provided around the cable core 1 is at least 1mm. thick. The mixing consistency of the consistent material is 85-475 when measured at room temperature by ASTM D-217, and there are grease such as polyurea grease and lithium soap grease as the hydrophobic material having mixing consistency.

摘要： PURPOSE:To raise a water running preventive effect by providing a layer of a water absorbing substance on the outside surface of a core of a water shielding type optical fiber which is packed with a packing material for preventing a water running, in a space in a cable core consisting of a lot of optical fibers and a space between the core and the sheath. CONSTITUTION:Layers 5.6 of a water absorbing substance are provided on the outside surface of a core 1 of a water shielding type optical fiber cable which is packed with a packing material for preventing a water running, in a space in a cable core 1 consisting of a lot of optical fibers and a space between the core 1 and a sheath 4. As for such a water absorbing substance, for instance, an organic matter of an acrylic acid denatured starch or an inorganic matter of an alumina gel, etc. is used. In this way, by providing the layer 5 or the layer 6 containing said water absorbing substance on a boundary of the core 1 which becomes easily a water running path and a packing layer 2 of a packing material for preventing a water running, for instance, even if an inundation occurs, the water absorbing substance of said layers 5.6 absorbs water, and a water running in the cable can be prevented. In this way, a water shielding type optical fiber cable having a high performance is obtained.

摘要： PURPOSE:To absorb intruding water by itself and to prevent running water by using a mixture composed of a hydrophobic material used as a base and a water absorptive material as a packing material for preventing the running water. CONSTITUTION:Eight pieces of optical fiber core units 1 each formed by gathering six pieces of optical fibers around a tensile member 11 such as a metallic wire and winding a tape 13 for retentive winding are gathered around a tensile member 2 and are covered with a water shielding layer 3 consisting of Al, etc. and an extruded protective sheath layer 4. A packing material 5 is packed in the inside space of the layer 3 and a mixture composed of a hydrophobic material and a water absorptive material is used as a packing material 5. Various hydrophobic materials such as polyurea grease, lithium soap grease, etc. are enumerated as the hydrophobic materials. The water absorptive material acts to prevent running water by absorbing the water by itself when the water intrudes to the inside of the layer 3. There are org. water absorptive materials such as polymer-grafted starch like acrylic acid modified starch, polymer-grafted cellulose, carboxymethyl cellulose, acrylic acid polymer, etc. and inorg. materials such as silica gel and quicklime as the water absorptive material.
