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： 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： Optical fibers are fixed to elongating tables by optical fiber fixing jigs. Coatings are removed from portions of the fibers and respective fibers of two different groups are placed into tight contact with one another. The fibers are then heated by a gas burner 4A so as to be welded integrally with each other, and are then elongated. In one preferred embodiment, the fibers are arranged such that there are gaps therebetween. These gaps are substantially 250 .mu.m. The gaps are sufficiently wide that heating gas flows in a manner such that all the optical fiber strands are heated uniformly to make it possible uniform welding and elongation.

摘要： Optical fibers are fixed to elongating tables by optical fiber fixing jigs. Coatings are removed from portions of the fibers and respective fibers of two different groups are placed into tight contact with one another. Rectifier rods, supported movably by rectifier rod supporting members, are disposed outside the optical fiber strands. The fibers are then heated by a gas burner 4A so as to be welded integrally with each other, and are then elongated. By using rectifier rods, the outside optical fiber strands of the groups being welded are not so strongly heated that uniform welding and elongation can be realized. In one preferred embodiment, the fibers are arranged such that there are gaps therebetween. These gaps are substantially 250 .mu.m. The gaps are sufficiently wide that heating gas flows in a manner such that all the optical fiber strands are heated uniformly to make it possible uniform welding and elongation.

摘要： A reinforced structure for a multicore optical fiber coupler wherein a longitudinal coating resin of first and second multicore optical fibers, each having a plurality of optical fiber stands positioned in parallel arrangement to each other and each collectively coated with a respective coating resin, is partially removed so as to expose glass portions of the optical fiber strands of each of the optical fibers. The exposed glass portions are then fused and extended. The fused and extended portions are then accommodated in a plurality of grooves formed in a reinforcing casing. The non-extended portions, which are located on opposite ends of the fused and extended portions in the extending direction, are also accommodated on the surface of the reinforcing casing. The optical fibers are secured to the reinforcing casing with adhesive, which is applied to the non-extended portions of the fibers. The reinforcing casing is preferably made of a material having substantially the same coefficient of linear expansion as that of quartz.
