摘要： A composite cable that is able to prevent both the unfastening of the cable end from the connector and the occurrence of the bending distortion of the optical fiber, to both of which the expansion and shrinkage of the overall sheath is responsible, is provided. The composite cable comprises a stranded wire that is a strand of a plurality of insulated conductors each of which is a conductor with insulation covering thereon, an optical fiber ribbon that has a plurality of optical fibers parallelly-arranged in a row, and an overall sheath that covers the stranded wire and the optical fiber ribbon in a bundle, wherein the composite cable has a deterrent positioned on outer side of the stranded wire and the optical fiber ribbon parallelly-arranged in a row along the width direction of the overall sheath for deterring expansion and shrinkage of the overall sheath. Further, the composite cable has a bonding jacket between the deterrent and the overall sheath for making the deterrent adhere to the overall sheath; alternatively, the deterrent has a patterned indented shape on the surface thereof for making the deterrent adhere to the overall sheath.

摘要： In an optical connector, end faces of a pair of ferrules that hold multiple optical fibers are positioned with two guide pins and butted against each other to connect the optical fibers in the pair of ferrules. The optical connector is provided with an urging member for pushing the end faces against each other. The end faces are ground at an angle. The gap between the guide pins and guide holes, which open at the end faces and into which the guide pins are fitted, is larger than 0.004 mm and smaller than or equal to 0.008 mm. Powder caused by the friction generated when the guide pins are inserted and fitted into the guide holes is greatly reduced. Connection loss does not increase even when frequent connection and disconnection are performed, and cleaning the connector becomes unnecessary.
