摘要： In an optical fibre submarine cable the ingress of hydrogen ions is reduced if not eliminated by at least one envelope which provides a barrier to hydrogen ions.In one embodiment a copper tape (L) is folded longitudinally around the cable core comprising strength member wires (G,H) split aluminium or coppr tube (E) and optical fibre package (A). The abutting edges (L') are seam welded with less than 0.1% skips. Preferably the folded copper tape is longitudinally welded while a loose fit and subsequently reduced in diameter to leave an accurately determined small annular gap between tubes E and F which is filled with a water blocking material that is highly viscose at ambient temperature and effectively glues the tubes together.In an alternative embodiment, or as a modification to the embodiment just described, the aluminium or copper tube (E) has its abutting edges (E') welded to a depth sufficient to provide the envelope (or a second such envelope) but insufficient to cause damage to the optical fibre package (A) through the heat from welding.

摘要： A lubricating composition and method are disclosed for lubricating the inner wall of a hollow conduit and the outer surface of an insulated flexible electrical conductor installed in the conduit. The lubricating composition is a powder comprised of the following powdered ingredients: lubricant such as talc; drying agent such as a micron-mesh silica; surfactant such as calcium stearate; odorant such as sassafras; and colorant such as a nontoxic food or cosmetic dye. The lubricating method first includes the step of blowing a quantity of a powdered lubricating composition into a hollow conduit resulting in the deposition of powdered lubricant on the inner wall of the conduit. In the next step of the method, an insulated flexible electrical conductor is inserted into the pre-lubricated conduit whereby powdered lubricant on the inner wall of the conduit rubs off onto the outer surface of the insulation of the electrical conductor thereby lubricating the insulation as it advances through the conduit.

摘要： An optical communication element comprises an optical fiber bonded in a state of axial compression to a metal tape. The tape may be folded up into a tube and sealed by soldering. Such elements are strong and not sensitive to stress corrosion. Such an optical communication element may be produced by passing a metal tape and an optical fiber in contact around a drum with the optical fiber on the outside. An adhesive, which solidifies or cures during the passage around the drum is applied to the metal tape.

摘要： In the manufacture of a lightguide fiber cable (21) in which a lightguide fiber core (32) is loosely disposed in a composite sheath 40 it is important to control the ratio of the lengths of the core and sheath. A core which is shorter than the sheath and which follows a shortened path on a reel may be unduly strained when the cable is installed in the field. This problem is overcome by coupling the core to the sheath by a system (25) which includes a constant speed linear capstan (146) and a relatively large variable speed sheave (150) that is positioned between the linear capstan and a takeup reel (154). The coupling of the core to the sheath is accomplished on the sheave after the sheath is elongated between the linear capstan and the sheave. The coupling and the elongation cooperate to compensate for the inherent shortfall in core length which otherwise would occur when the cable is wound on a reel. As a result, when tension forces that have been applied to the sheath are reduced, the sheath, which includes strength members having a relatively high modulus of elasticity, recovers to its original length and the ratio of the length of the core to that of the sheath becomes a predetermined value.
摘要翻译：在制造其中光导纤维芯（32）松散地设置在复合护套40中的光导纤维电缆（21）时，重要的是控制芯和芯的长度比。当电缆安装在现场时，短于护套并且沿着卷轴上的缩短路径的芯可能不适当地变紧。通过将系统（25）耦合到护套来克服该问题，该系统包括恒速线性绞盘（146）和位于线性绞盘与收紧卷轴（154）之间的相对较大的可变速度滑轮（150））。在护套在线性绞盘和滑轮之间延伸之后，芯线与护套的耦合在滑轮上完成。耦合和伸长率协调以补偿当电缆缠绕在卷轴上时将发生的芯长度的固有不足。结果，当已经施加到护套的张力减小时，包括具有相对较高弹性模量的强度构件的护套恢复到其原始长度，并且芯的长度与护套成为预定值。

摘要： A glass fiber for use as a light waveguide characterized by a one piece member having at least one transverse opening extending through the fiber to subdivide a section of the fiber into two portions connected at each end by the zones of the fiber free of the opening. By cutting in the area of the opening, a branch fiber can be produced. Preferably, the fiber includes a pair of cores which are separated by the openings. The method includes drawing the fiber from a mass of softened glass and while in the softened state, forming the openings therein or by drawing the fiber from a preform having at least one transverse extending opening. Preferably the preform is formed by joining two members having flat surfaces together and the openings in the preform are formed by forming transverse grooves in one of the flat surfaces.
