摘要： PURPOSE:To provide optical fibers with sufficient surplus length and enable shrinking of the outside dia. of an OP unit by winding or laying longitudinally a tape which forms a foaming layer partially at the periphery of a bundle of optical fibers, and foaming the foaming layer when it is covered with an aluminum pipe. CONSTITUTION:Foaming agents 3a, 3a are pinched partially between two polymid tapes 2, 2. Optical fibers 1a, 1a are twisted or bundled into a bundle of optical fibers 1, and at its periphery the tapes 2 having foaming agent 3a are wound or laid longitudinally. This is heated to allow the agent to foam, and a foam layer 3 is provided. The tapes themselves deform into corrugated form, and accordingly the inside bundle of optical fibers 1 are deformed into corrugated form, to equip the fibers 1a, 1a with a surplus length on the basis of the corrugated form. An aluminum pipe 4 is laid over this surplus length to constitute an OP unit 10.

摘要： PURPOSE:To prevent the application of stress to an optical fiber by inserting the optical fiber into a spirally grooved spacer on the outside circumference of a tension member given which is applied with untwisting while rotating the fiber in the direction where the groove pitch of the spirally grooved spacer decreases, then coating a sheath thereon. CONSTITUTION:The arbitrary untwisting is previously applied to the tension member 2 and the spirally grooved spacer 3 is provided on the outside circumference of this member. The optical fiber 1 is inserted into this spacer 3 while the fiber is rotated in the direction where the groove pitch of the spacer 3 decreases. The sheath is coated on the outside circumference of the spacer 3 after the insertion, then the untwisting applied to the member 2 is released. The surplus length is thereby easily provided to the optical fiber 1 and the application of the stress on the optical fiber 1 is easily prevented.

摘要： PURPOSE:To connect optical fibers easily by matching the axes of the 1st and 2nd optical fibers by an axis matching mechanism in an optical fiber connector on the basis of an output from a differential amplifier. CONSTITUTION:The 1st and 2nd bent parts 10, 11 obtained by bending the 1st and 2nd optical fibers 1a, 2a are formed on the side of the optical fiber connector 9. Light rays incident upon the 1st and 2nd bent parts 10, 11 are leaked and the leaked light rays are converted into electric values by the 1st and 2nd optical power detectors 12, 13 arranged oppositely to the 1st and 2nd bent parts 10, 11. The converted electric values are inputted to the differential amplifier 14 connected between the 1st and 2nd optical power detectors 12 and 13 and the axis matching mechanism of the optical fiber connector 9 is adjusted by an output from the differential amplifier 14 which is based upon said inputs. Thus, the optical fibers 1a, 2a can be easily connected.
