    • An improved self-supporting fiber optic cable is provided that includes a cable section having at least one optical fiber and a jacket surrounding the at least one optical fiber, and a support section having at least one strength member extending in a lengthwise direction and an overlying jacket that includes a number of jacket segments spaced lengthwise along the at least one strength member. As a result of the lengthwise spacing of the jacket segments, portions of the at least one strength member are at least partially exposed. The jackets of the cable and support sections are connected, such as by an intermittent web. A method for manufacturing a fiber optic cable having a support section with an intermittent or semi-intermittent jacket is also provided which relies upon the periodic extrusion of extrudate about the at least one strength member to form the jacket segments that are spaced apart in a lengthwise direction along the at least one strength member. Alternatively, a thin coating of jacket material can exist between jacket segments.
    • 提供了一种改进的自支撑光纤电缆,其包括具有至少一个光纤的线缆部分和围绕该至少一根光纤的护套,以及支撑部分,其具有沿长度方向延伸的至少一个强度部件和上覆 护套,其包括沿着至少一个强度构件沿纵向间隔开的多个护套段。 由于护套段的长度间隔的结果,至少一个强度构件的部分至少部分暴露。 电缆和支撑部分的夹克连接,例如通过间歇网。 还提供了一种用于制造具有间歇或半间歇夹套的支撑部分的光缆的方法,其依赖于围绕所述至少一个强度构件的挤出物的周期性挤出以形成沿长度方向间隔开的护套段 方向沿着至少一个强度构件。 或者,套管材料的薄涂层可以存在于护套片段之间。

    • A self-supporting fiber optic cable includes messenger and carrier sections and at least one interconnecting web. The messenger section includes at least one support member and a protective jacket. The carrier section includes a tube, at least one optical fiber disposed within the tube, and a jacket. In order to protect the optical fiber from tensile forces and to facilitate mid-span access, the carrier section can have an overlength. In order to accommodate the overlength, the web can include a plurality of intermittent webs that permit the carrier section to bend. The carrier section can also include at least one strength member. The at least one strength member is preferably positioned in a reference plane that also generally extends through the messenger section, the carrier section and the web. By appropriately positioning the strength members relative to the tube, the carrier section preferentially bends in a plane generally orthogonally disposed to the reference plane. As a result, the fiber optic cable not only accommodates the overlength of the carrier section, but also facilitates the winding of the fiber optic cable upon a reel for shipment and storage.
    • 自支撑光缆包括信使和载体部分以及至少一个互连网。 信使部分包括至少一个支撑部件和防护套。 载体部分包括管,设置在管内的至少一个光纤和夹套。 为了保护光纤免受拉力的影响,并且便于中跨接口,载体部分可以具有超长度。 为了适应超长度,幅材可以包括允许载体部分弯曲的多个间断纤维网。 载体部分还可以包括至少一个强度构件。 优选地,至少一个强度构件定位在参考平面中,该参考平面也通常延伸穿过信使部分,载体部分和腹板。 通过相对于管适当地定位强度构件,载体部分优选在大致正交地设置在参考平面上的平面中弯曲。 结果,光纤电缆不仅容纳载体部分的长度,而且还有助于将光纤线缆缠绕在卷轴上用于装运和存储。

    • A fiber optic ribbon having a plurality of optical fibers held together by a matrix material is disclosed. The matrix material has a first end with a first shape and a second end with a second shape, where the first shape is different than the second shape. In one embodiment, the first end has a concave end portion and the second end has a convex end portion. The fiber optic ribbon is advantageous as a subunit of a larger ribbon since the first end of a first subunit can interlock with a second end of a second subunit, thereby providing a robust structure. Moreover, the distance between optical fibers of adjacent subunits is reduced so the fiber optic ribbon may allow mass fusion splicing of same using standard splice chucks.
    • 公开了一种具有由矩阵材料保持在一起的多个光纤的光纤带。 基体材料具有第一形状的第一端和具有第二形状的第二端,其中第一形状不同于第二形状。 在一个实施例中,第一端具有凹入端部,第二端部具有凸出的端部。 由于第一子单元的第一端可以与第二子单元的第二端互锁,从而提供了坚固的结构,因此光纤带作为较大带的子单元是有利的。 此外,相邻子单元的光纤之间的距离减小,因此光纤带可以允许使用标准拼接卡盘进行大量熔接。
