摘要： A buffer tube for an optical fiber cable is made from a polypropylene-polyethylene copolymer resin having nucleating agents and filler materials disbursed therein. The nucleating agents and filler materials improve compression-tension resistance and thermal expansion properties of the polypropylene-polyethylene copolymer buffer tube (32). A non-armored cable structure incoporates the present invention and is generally indicated by the numeral (30). This structure includes a single, large, gel-filled buffer tube (32) made of a polypropylene-polyethylene copolymer at least incorperating a nucleating agent. The gel in the buffer tube is a thioxotropic, water-blockable gel. The gel-filled buffer tube (32) contains a plurality of optical fibers (34). Radial strength yarns (36), made from either aramid, polyethylene, polyester, or fiberglass materials, are contra-helically stranded around the buffer tube (32) and impregnated with filling compounds such as a petroleum based hot melt filling compound. Two metallic or dielectric strength members (38) are located 180 degrees apart on the outside of the radial strength yarns (36). A high strength rip cord (40) is applied over the radial strength yarns (36) to aid in sheath removal. A medium-density polyethylene (MDPE) outer jacket (42) encapsulates the strength members (38) and radial strength yarns (36) to complete the structure. The MDPE of jacket (42) may be filled with carbon black powder.

摘要： A communication cable, such as a fiber optic cable, can comprise a conductive tape that extends along the cable and that facilitates locating the cable from a remote location, for example when the cable is buried under ground. The tape can comprise a low resistance for transmitting a locate signal along the length of the cable that can be detected remotely by a detector without exposing the cable. The conductive tape can be circumferentially applied around the core of the cable under the cable's jacket. Thus, the conductive tape can be accessed without exposing the core. The cable can include one or more buffer tubes for housing optical fibers. The buffer tubes and/or the jacket can comprise an antioxidant for preventing degradation associated with contact with copper or other metal of the conductive tape.

摘要： A fiber optic cable can inhibit water that may inadvertently enter the cable from flowing lengthwise within the cable. The fiber optic cable can include a buffer tube defining an interior volume extending along the cable. Water blocking barriers can be disposed in the buffer tube intermittently along the length of the cable. The barriers can be formed from a UV and thermal cured material and can comprise an acrylic. The barriers can be applied to the optical fibers or to a carrier tape that is wrapped around the optical fibers or fiber bundle. The barriers (or carrier tape) can be disposed against and/or adhere to an inner surface of the buffer tube to provide intermittent water blocking. Each barrier can provide a seal around the optical fibers and can limit flow of water in the interior volume.

摘要： A tape can comprise a strip of dielectric material, with adhering patches of electrical conductive material. The patches can be substantially electrically isolated from one another. The strip can be disposed in a communication cable to provide a shield that is electrically discontinuous or has high resistance between opposite cable ends. Each patch can interact with electromagnetic radiation associated with electrical signals transmitting over the cable. The patches can collectively interact with the transmitting electrical signals in a cumulative or resonant manner to produce a spike in return loss at a particular frequency of the transmitting signals. The frequency location of the spike can depend upon the sizes of the patches, with size impacting manufacturability. The patches can be sized such that the spike falls within an operating frequency of the transmitting signal but is suppressed, so the cable meets return loss specifications while offering manufacturing advantage.
摘要翻译：胶带可以包括电介质材料条，具有导电材料的附着贴片。贴片可以基本上彼此电隔离。带可以设置在通信电缆中，以提供电连接的屏蔽或在相对的电缆端之间具有高电阻。每个贴片可以与通过电缆传输的电信号相关联的电磁辐射相互作用。补片可以以累积或共振的方式与发射电信号共同交互，以在发射信号的特定频率产生回波损耗的尖峰。尖峰的频率位置可以取决于贴片的尺寸，其尺寸影响可制造性。这些贴片的尺寸可以使得尖峰落在发射信号的工作频率内，但被抑制，因此电缆在提供制造优势的同时符合回波损耗规格。

摘要： A fiber optic cable can inhibit water, that may inadvertently enter the cable, from damaging the cable's optical fibers. The fiber optic cable can comprise buffer tubes extending along the fiber optic cable. The buffer tubes can be arranged such that a ring of buffer tubes surrounds one or more centrally located buffer tubes. Stacked ribbons of optical fibers can be disposed in each buffer tube, along with water-swellable tape and water-swellable yarn. The tape, yarn, and optical fibers can be dry or free from water-blocking gels or fluids. The water-swellable materials can provide an unexpected level of water protection. The water-swellable materials can, for example, limit flow of seawater within the buffer tubes. In an exemplary embodiment, progression of seawater can be limited to three meters or less for a twenty-four hour test period during which the seawater is under about one meter of head pressure.
