Abstract: A fibre optic separator has a housing (10) with input and output ports (11, 12). The input port (11) has one or more channels (31, 32) through which a fibre optic cable may enter the housing. The output port (12) has one or more passages (66-91) through which one or more optical fibres may exit the housing. Each channel/passage has an associated formation (35-38, 94-97) for retaining the protective casing, sheath, tube or the like which surrounds the optic cable/fibre, relative to the housing. The associated formation (35-38, 94-97) acts to relieve strain in the cable/fibre and may partly penetrate and/or frictionally or otherwise engage the protective casing, sheath, tube or the like.

Abstract: An apparatus is disclosed for laying cables below a sea bed or an ocean bed. Energy is supplied from a surface vessel to said apparatus, allowing said apparatus to vibrate with sufficient energy to produce a localised fluidized region. The cable is then placed into the sea bed by directing it into said fluidized region. Although energy is required to produce the fluidized region, the energy required to tow the apparatus and effect the laying processes is substantially reduced, compared to previously known techniques.

Abstract: The invention is an improved sleeve (2) that includes a wire (4) inserted through the length of the sleeve (2) before the sleeve is mounted on a bobbin (8). The wire (4) keeps the sleeve (2) relatively kink free and removes any debris which may have been in the sleeve (2). The wire is removed from the sleeve (2) and allows an optical fiber to be easily inserted into the sleeve (2) to start winding of the optical fiber onto the bobbin (8).

Abstract: This invention relates to an optical fiber cable (20). To reduce the diameter of the cable (20), high tensile strength synthetic resin fibers are bundled to obtain a bundle (23) and the outer periphery of the bundle (23) is covered with a synthetic resin coating (24) to obtain a core (22). Helical grooves (25) for receiving and accommodating optical fiber core wires (21) are formed on the core (22) in a longitudinal direction. The optical fiber cable (20) is produced by using this core (22). When the optical fiber core wires (21) are inserted into the helical grooves (25), the invention provides a method of producing the optical fiber cable (20) in which the core (22) is held to eliminate any fluctuation of the optical fiber core wires (21) occurring in the rotating direction around the axis of the core (22) and in which the optical fiber core wires (21) are stably inserted.

Abstract: A spacer for supporting an optical fiber having helical grooves (A) whose helical direction reverses alternately per turn and which encases optical fibers, wherein the helical groove (A) includes extra-length parts (1, 1') formed at an angle smaller than the helical angle of main parts (3, 3') with respect to a neutral axis and compensation parts (2, 2'), said extra-length parts being disposed at the respective positions of helical direction reversion and said compensation parts being disposed at the positions between the adjacent extra-length portions in the longitudinal direction and between 1/4 turn and 3/4 turn with respect to respective helical directions with the respective positions of helical direction reversion as starting points. According to this arrangement, even when the spacer is curved, the occurrence of the stress difference in the longitudinal direction between the optical fibers can be minimized.

Abstract: The propulsive force on an optical transmission line member (25) moving through a tubular passageway (11, 11') can be varied so the line travels at or close to optimum speed without risk of damage to the line or associated apparatus. A curve is provided in a portion of the passageway such that a transmission line subject to unacceptable compressive forces buckles towards the outer side of the curve. A sensor (49, 51) detects the presence or absence of the line at this point and a control circuit (23) varies the propulsive force. Excessive tension in the fibre may also be detected. A modified system uses deflectors to ensure that buckling occurs by bowing in the direction towards the sensor with the transmission line undeflected under correct tension. The invention finds particular application in a method or fibre blowing where an optical fibre transmission line is propelled along a tube by fluid drag.

Abstract: Fiber optic solderable bulkhead fitting has a plated-on built-up metal body (18) of a material which minimizes local stresses thereby minimizing micro-bending losses in the optical fiber (10). The body (18) is sealed by solder (24) within an opening (22) in a bulkhead (20) to provide a sealed passthrough for the optical fiber (10). In another embodiment, two optical fibers (26, 28) have plated-on built-up bodies (30, 32) thereon which serve to align the optical fibers in a connector (42). The connector (42) is then sealed in a bulkhead (38) as was done in the first embodiment.
