摘要： A communication cable having a communication wire and an armor including at least two synthetic resin layers, and protects the communication wire in a loose state. The communication wire protecting tube includes at least two synthetic resin layers, and inserts the communication wire in a loose state. The most hard resin layer of the armor has a crosswise or spiral annular groove or cut portion continuous in the longitudinal direction to reach the radially inner face, and the outermost layer of the armor is formed of a protective layer made of a softer resin than the hard resin layer. The adjoining edge portions of the annular groove or the cut portion come, when the communication wire is to be bent, into contact with each other so that it may be prevented from being bent to a predetermined or smaller bend radius.

摘要： [Problems to be solved]A communication cable and a communication wire protecting tube, which can be easily bent to a predetermined bend radius by a low force but which requires such a higher force for the bend of a smaller diameter that it may be hard to bend. [Means for solving the Problems]The communication cable 10,10A comprises a communication wire 11,11A and an armor 13A including at least two synthetic resin layers, and protects the communication wire 11,11A in a loose state. The communication wire protecting tube comprises at least two synthetic resin layers, and inserts the communication wire 11,11A in a loose state. The most hard resin layer 13a, 13aA of the armor 13,13A has a crosswise or spiral annular groove 14 or cut portion 14A continuous in the longitudinal direction to reach the radially inner face, and the outermost layer of the armor 13,13A is formed of a protective layer 13b,13bA made of a softer resin than the hard resin layer 13a, 13aA. The adjoining edge portions 14a,14aA of the annular groove 14 or the cut portion 14A come, when the communication wire 11,11A is to be bent, into contact with each other so that it may be prevented from being bent to a predetermined or smaller bend radius.

摘要： A plurality of optical fibers are arranged in parallel and peripheries of the plurality of these optical fibers are integrally formed using a sheath. Here, the sheath is formed over the entire length of optical fiber ribbons and a flat portion of the sheath is formed substantially parallel to a common tangent of the neighboring optical fibers. A maximum value of a thickness of the optical fiber ribbons is set to a value which is larger than an outer diameter of the optical fibers by 40 μm or less. Due to such a constitution, it is possible to easily branch the optical fibers from the integrally formed optical fiber ribbons.

In particular, the sensor section has a structure such that the variation of the Brillouin spectrum in response to a disturbance differs between the waveguides. Thus, by simultaneously monitoring the Brillouin spectra that varying a different manner in a plurality of waveguides, it is possible not only to measure accurately the temperature in a wide temperature range including a low-temperature region, but also to make distinction between the strain and temperature.
