摘要： The present invention relates to a sensor or the like having a structure that enables accurate temperature measurement in a wide temperature range including a low-temperature region and is suitable for independently and accurately determining temperature variations and strains appearing in an object to be measured. The sensor comprises a laser light source, a sensor section that has a plurality of waveguides transmitting a laser light from the laser light source therethrough, a detecting section, and an analyzing section. The detecting section detects a plurality of Brillouin spectra obtained from the sensor section. The analyzing section determines at least one measurement value of a temperature in the sensor section and a strain generated in the sensor section, based on fluctuations of parameters defining the respective detected Brillouin spectra. 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.

摘要： The present invention relates to a wide-band, low-loss, submarine optical cable excellent in productivity, an optical fiber unit employed in the submarine optical cable, and a method of making the optical fiber unit. The optical fiber unit employed in the submarine optical cable comprises a loose structure in which one or more coated optical fibers are accommodated together with a soft resin in a space formed within a plastic support. In particular, one or more compression members are embedded in the plastic support along the space accommodating the coated optical fibers. The compression members closely in contact with the plastic support prevents the shrinkage of the plastic support from occurring due to temperature changes before forming a cable utilizing the optical fiber unit. Preventing the shrinkage of the plastic support from occurring before forming the cable suppresses the increase in surplus length ratio of the accommodated coated optical fibers, thereby effectively restraining the transmission loss of the submarine optical cable from increasing due to the increase in surplus length ratio.
摘要翻译：本发明涉及生产率优良的宽带，低损耗海底光缆，在海底光缆中使用的光纤单元以及制造光纤单元的方法。在海底光缆中使用的光纤单元包括松散结构，其中一个或多个涂覆的光纤与柔性树脂一起容纳在形成在塑料支撑体内的空间中。特别地，一个或多个压缩构件沿着容纳涂覆光纤的空间嵌入在塑料支撑件中。紧密地与塑料支撑件接触的压缩构件防止在形成利用光纤单元的电缆之前由于温度变化而发生塑料支撑件的收缩。防止在形成电缆之前发生塑料支撑件的收缩，抑制了被容纳的被覆光纤的多余长度比的增加，从而有效地抑制了由于冗余长度比的增加导致的海底光缆的传输损耗的增加。

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： 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.
