摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cable capable of assuring stable transmission characteristics even against disturbance, such as bending and temp. change, by preventing positional deviation of a unit. SOLUTION: This optical fiber cable is formed by laminating and inserting 8-core optical fiber ribbons into an S-Z spiral spacer (an S-Z inversion angle 300 deg., inversion pitch 360 mm) made of high-density polyethylene(HDPE) and closely winding wrapping tapes (nonwoven fabrics) thereon. While 10 sheets each of the 8-core optical fiber ribbons are packaged into a single-groove unit body 10 (made of a PBT resin having a coefft. of bending elasticity of 160 kg/mm ), 15 pieces thereof are stranded to an S-Z form (S-Z inversion angle 300 deg. and inversion pitch 360 mm) around the outer periphery and, thereafter, the wrapping tapes (nonwoven fabrics) are closely wound around its outer periphery. Further, a PE sheath is applied on the outer periphery thereof. In such a case, the bottom surface of the unit bodies 10 used for the optical fiber cable are formed to a suitable matte state and the surface roughness thereof is 2.6 μm in roughness average.

摘要： PROBLEM TO BE SOLVED: To prevent positional deviation of a resin unit. SOLUTION: The synthetic resin unit 10 is formed of a thermoplastic resin over the entire part and has a recessed housing groove 12 for housing a prescribed number of optical fibers or optical fiber ribbons formed in its central part. The unit is formed into a substantially U shape in its cross section. This housing groove 12 is formed with S-Z twists of the same inversion angle and twist pitch as those of a spiral spacer. The synthetic resin unit 10 is formed by stranding plural pieces of the fibers or ribbons to the S-Z form on the outer periphery of the spiral spacer or tension member in the state of tight contact with each other in the circumferential direction. The unit 10 is packed with a groove packing resin 16 consisting of a peelable thermoplastic resin which does not exhibit compatibility with the thermoplastic resin of the unit 10 even in a fused state by co-extrusion on the circumference thereof around a tensile strength member 14 in the housing groove 12.

摘要： PURPOSE:To butt end surfaces of optical fibers against each other while evading the occurrence of trouble by setting the end surfaces of the optical fibers on both surfaces of an abutting plate in abutting relation and then jogging both optical fibers in the opposite directions of the abutting directions, and moving the abutting plate back and moving both optical fibers relatively. CONSTITUTION:The optical fibers 10A and 10B are moved in their abutting directions through slip holders 8A and 8B, and the end surfaces of optical fiber end parts 11A and 11B are set on both surfaces of the abutting plate 6 in abutting relation. Both optical fibers 10A and 10B are jogged in the opposite directions of the abutting directions to separate both optical end surfaces from the abutting plate 6. Consequently, there is no trouble when the abutting plate 6 leaves both optical fiber end surfaces. Then, the optical fiber end parts 11A and 11B are moved relatively in the abutting directions and welded together.

CONSTITUTION:The coater 5 having the tip dipped in a liquid tank 7 moves up by specific distance by the quantitative rotaion of a cam 6, part of the matching liquid 8 in the liquid tank 7 sticks on the projection 9 atop the coater and is carried in the same direction, and the matching liquid 9 sticking on the projection part 9 comes into contact with optical fiber end surfaces 4A and 4B. Then, the coater 5 moves down toward its original position by the cam rotation, and a specific amount of matching liquid 9 is left between both end surfaces 4A and 4B. Then, alignment is carried out to obtain the aligned state between optical fibers 1A and 1B, and then both optical end parts 3A and 3B are moved relatively in abutting directions and fusion heat is supplied from a specific machine to weld the end parts 3A and 3B together.

摘要： PURPOSE:To supply a proper amount of matching oil by positioning the tip part of a rod- or plate-shaped body between optical fibers and utilizing capillarity. CONSTITUTION:The matching oil 48 put in a pot 38 moves round to a gap 46 through the hole 42 in a nozzle 40 with a stopper 30 lowered, and reaches the lower end of a slit 36 and rises to stick of flanks of an abutting plate 31 and a shoulder 34 in a mountain shape by the ''wetting'' operation upon the stopper 30 and surface tension operation. The stopper 30 is elevated in this state and an optical fiber 14 facing the abutting plate 31 is moved forth, so that the matching oil 48 sticks on its front end surface. Then when the stopper 30 is lowered, the matching oil 48 sticking atop of optical fibers 14 stick mutually and the interval between the optical fibers 14 is as long as the specific length right before discharging is started. Then, the matching oil 48 is supplied to the stopper 30 and the matching oil 48 is supplied subsequently and automatically.

摘要： PURPOSE:To adhere matching oil easily by lifting approximately parallel plate- like bodies enabled to hold matching oil by surface tension to adhere the oil to the end surfaces of optical fibers aligned with the positional relation of connection. CONSTITUTION:The optical fibers 1, 4 are held by holders which are not shown in the drawing with the positional relation of connection. Two plate-like bodies 19, 20 are arranged approximately in parallel with an interval enabled to hold the matching oil 17 by the surface tension. The plate-like bodies 19, 20 are dropped into an oil tank 16, soaked with the oil 17 and then lifted up so that the connection part 14 of the optical fibers 1, 4 are soaked with the oil included in the plate-like bodies 19, 20. Consequently, the proper quantity of oil is applied to the end surfaces of the fibers 1, 4 and the end surfaces can be connected with each other efficently.
