摘要： A process for producing an optical fiber cable composite structural component, such as reinforcing members, buffer tubes, filler rods, jackets, and slotted cores, is disclosed. The composite structural components are produced by co-extruding a thermotropic liquid crystalline polymer (TLCP) and a thermoplastic matrix material into the composite structural component so that TLCP reinforcing fibrils are dispersed in the thermoplastic matrix material. The TLCP reinforcing fibrils undergo a high level of process induced orientation, are provided with a high aspect ratio, and small diameters. The composite structural component has a high modulus. The TLCP reinforcing fibrils may be made continuous or discontinuous.

摘要： Disclosed are tight-buffered and semi-tight-buffered optical fiber units. The optical fiber unit includes an optical fiber that is surrounded by a polymeric buffering layer to define a fiber-buffer interface. The buffering layer includes an aliphatic amide slip agent in an amount sufficient for at least some of the aliphatic amide slip agent to migrate to the buffer-fiber interface to thereby promote easy stripping of the buffering layer. For example, at least about 15 centimeters of the polymeric buffering layer can be removed from the optical fiber in a single operation using a strip force of less than about 10 N.

摘要： An aerial drop cable comprises a jacket surrounding a cavity containing a least one loosely housed optical fiber and a pair of reinforcing members composed of a plurality of high modulus fibers such as polybenzoxazole (PBO) fibers. The cross-sectional area of the reinforcing members is larger than the cross-sectional area of the cavity so that the optical fiber disposed in the cavity is protected from lateral compressive forces. By utilizing reinforcing members which are composed of PBO fibers, the diameter of the reinforcing members is reduced as compared with conventional reinforcing members composed of aramid, metal or glass thereby providing a substantial reduction in the amount of jacketing material and the weight of the cable. Further, the bending strain of the cable utilizing PBO reinforcing members is substantially reduced for an equivalent bending radius as compared with cables utilizing conventional reinforcing members due to the smaller diameter of the reinforcing members. Therefore, the bending radius of the cable is reduced providing greater flexibility for routing the cable.
摘要翻译：航空电缆包括围绕包含至少一个松散容纳的光纤的腔的护套和由多个高模量纤维如聚苯并恶唑（PBO）纤维构成的一对加强构件。加强构件的横截面面积大于空腔的横截面积，使得设置在空腔中的光纤被保护免受横向压缩力的影响。通过使用由PBO纤维构成的加强构件，与由芳族聚酰胺，金属或玻璃构成的常规加强构件相比，加强构件的直径减小，从而大大减少了护套材料的数量和电缆的重量。此外，由于加强构件的较小直径，与利用常规加强构件的电缆相比，利用PBO加强构件的电缆的弯曲应变基本上减小了等同的弯曲半径。因此，电缆的弯曲半径减小，为电缆布线提供了更大的灵活性。
