摘要： In a strain sensor and a method for installing a strain sensor according to the present invention, a first base fixes and supports one side of an optical fiber. A second base fixes and supports another side of the optical fiber. A connecting member is constituted of a separate member from the first base and the second base and is detachably mounted between the first base and the second base. Tension is applied to the optical fiber in a state in which the connecting member is mounted between the first base and the second base, and the optical fiber is fixed to and supported by the first base and the second base in a state in which tension is applied.

摘要： A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location, such as a multi-fiber connector, is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at one or more single or multi-fiber connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the connectors adjacent the front of the body includes a ferrule. Dark fibers can be provided if not all fiber locations are used in the multi-fiber connectors. Multiple flexible substrates can be used with one or more multi-fiber connectors.

摘要： A mixture of a urethane monomer and a urethane oligomer having a group represented in Fig. 4 and a polymerization initiator, which is a precursor of an elastomer exhibiting a flexural modulus of elasticity of 1,000 MPa or less after curing, is used as a clad material. The clad material is applied on a base plate and is pressed from above by a stamper and is spread into a thin film. After the clad material is cured to form an under clad layer, a core is formed on the under clad layer. Then, the above clad material is applied on the under clad layer, is pressed by a stamper from above and is spread into a thin film. The latter clad material is cured to form an upper clad layer. Finally, the base plate is removed, and a film optical waveguide capable of being bent with a small radius of curvature is obtained.

摘要： The present invention is directed to improving the yield in fiber terminating processing, and to preventing the occurrence of transmission loss due to stress concentration at an optical fiber bend or due to variations in ambient temperature. In one exemplary embodiment, a channel (14) is sandwiched between adhesive layers (16) and an optical fiber (12) is passed through the channel.
