摘要： A coaxial, fiber optic, or twisted pair cable having a is core surrounded by an armor layer and an outer protective jacket such that relative movement between the armor layer and the protective jacket is permitted. The armor layer has a pair of opposing longitudinal edge portions and is wrapped around a cable core such that a longitudinally extending seam is produced. The outer surface of the armor layer has an adhesive layer disposed thereon for bonding an outer protective jacket thereto. Portions of the outer surface of the armor layer adjacent the longitudinally extending seam are oxidized, thereby effectively neutralizing the adhesive layer. The oxidized portions of the armor layer reduce, if not eliminate, adherence between the protective jacket and the armor layer along the longitudinally extending seam.

摘要： A fiber optic cable according to the present invention includes at least one lengthwise extending channel surrounding an elongate central support member with each channel defining a channel axis. At least one optical fiber is positioned within each channel and has an average position offset in a direction generally radially inward from the channel axis toward the central support member at about room temperature. In one embodiment, the at least one channel is defined by one or more buffer tubes stranded about the central support member. In another embodiment, the at least one channel is defined by core having one or more lengthwise extending slots. The fiber optic cable may also include a protective jacket surrounding the central support member and the channel defining means. The optical fibers typically have a coefficient of thermal expansion less than the respective coefficient of thermal expansion of at least one of the protective jacket, the channel defining means and central support member. Thus, by offsetting the average position of the optical fibers at about room temperature in a direction extending generally radially inward from the channel axis, the thermal contraction window of the fiber optic cable is thereby increased. The fiber optical cable of the present invention thus provides consistent optical signal transmission performance over a predetermined range of temperatures and as the cable is placed under tensile loads up to a predetermined maximum load due to the optimized elongation and contraction windows.
摘要翻译：根据本发明的光纤电缆包括围绕细长中心支撑构件的至少一个纵向延伸通道，每个通道限定通道轴线。至少一个光纤位于每个通道内，并且在大约室温下具有从通道轴线向中心支撑构件大致径向向内的平均位置偏移。在一个实施例中，至少一个通道由围绕中心支撑构件绞合的一个或多个缓冲管限定。在另一个实施例中，至少一个通道由具有一个或多个纵向延伸槽的芯限定。光纤电缆还可以包括围绕中心支撑构件和通道限定装置的保护套。光纤通常具有小于保护套，通道限定装置和中央支撑构件中的至少一个的相应热膨胀系数的热膨胀系数。因此，通过在从通道轴线大体上径向向内延伸的方向上将光纤的平均位置偏移在大约室温下，由此增加了光纤电缆的热收缩窗口。因此，本发明的光纤光缆在预定的温度范围内提供一致的光信号传输性能，并且由于优化的伸长和收缩窗口，电缆被置于高达预定最大载荷的拉伸载荷下。

摘要： A composite fiber optic and electrical cable having a core which loosely contains at least one optical fiber, one or more electrical conductors having an outer polymer insulating layer, one or more strength members and a surrounding protective jacket. The protective jacket is formed of a polymer material which forms a distinct mechanically separate phase from the polymer material forming the insulation layer surrounding the respective electrical conductors. For example, the jacket can be made of a polymer material having a melting temperature lower than the melting temperature of the insulating material of the electrical conductors. As a result, the polymer jacket does not bond with the insulating material during production of the cable. The jacket can, thus, be easily stripped from the electrical conductors during installation of the cable to facilitate the attachment of the electrical conductors to a signal repeater, or power source, or other electrical devices. The cable is manufactured by advancing the core, the electrical conductors and the strength members through an extruder which forms the protective jacket thereabout. The core can be supplied from a storage reel or can be fabricated in-line just prior to extruding the jacket around the buffer tube, the electrical conductors and the strength members, by extruding a buffer tube loosely around the optic fibers.
摘要翻译：一种复合光纤和电缆，其具有松散地包含至少一个光纤的芯，一个或多个电导体，其具有外聚合物绝缘层，一个或多个强度构件和周围保护套。保护套由聚合物材料形成，该聚合物材料与形成围绕各个电导体的绝缘层的聚合物材料形成明显的机械分离相。例如，夹套可以由熔化温度低于电导体的绝缘材料的熔化温度的聚合物材料制成。结果，聚合物护套在制造电缆期间不与绝缘材料结合。因此，在安装电缆期间，护套可以容易地从电导体剥离，以便于将电导体连接到信号中继器或电源或其它电气设备。电缆是通过在其周围形成保护套的挤出机推进芯，电导体和强度构件来制造的。核心可以从存储卷轴提供，或者可以在将护套围绕缓冲管，电导体和强度构件挤出之前通过在缓冲管上松动地挤出光纤而在线制造。

摘要： An aerial self-supporting fiber optic cable includes a pair of longitudinal strength members extending along respective opposite sides of a core, and a jacket surrounding the core and strength members, wherein the jacket has a generally elliptical outer cross-sectional shape. A major transverse axis of the generally elliptical jacket is generally aligned with an imaginary line defined between the pair of longitudinal strength members. The cable core includes at least one elongate buffer tube and at least one optical fiber disposed within the buffer tube. The strength members has a predetermined tensile strength to support the fiber optic cable between adjacent vertical supports. The jacket may have a generally elliptical shape with an enlarged central lobe surrounding the core, and a pair of relatively smaller lobes on opposite sides of the central lobe and surrounding respective longitudinal strength members. An armor layer surrounds the core and provides protection for below ground installation of the cable as well. The fiber optic cable is also preferably flexible to facilitate twisting thereof between adjacent vertical supports to define a more irregular shape for wind passing over the fiber optic cable to thereby reduce wind-induced motion of the cable. An apparatus and method for making the cable are also disclosed.
