摘要： A method for manufacturing a cable and a cable assembly includes providing particulate matter within a tube extruded about an optical fiber (22). The particles may be accelerated so that as they strike the tube they mechanically attach to the tube. Powder particles are accelerated in a motive gas through a nozzle, along the process direction (12), to an interior of an extrusion cone where the powder particles have sufficient momentum to collide with the interior of the extrusion cone. The acceleration is such that at least a portion of the powder particles becomes mechanically attached to the extrusion cone. The tube can be included with other such tubes to form a fiber optic cable.

摘要： A method of forming a low-cost drop cable (10) is disclosed. The method includes providing a protective cover material (352) having an extrusion temperature of 140°C ≤ TE ≤160°C. The protective cover material is extruded through a die (420) having a single aperture (424) that defines the cable's elongate cross-sectional shape. The extrusion process involves covering first and second strength members (30) on either side of at least one optical fiber (50). The combination of the low temperature of the extrudable protective cover material and the elongate shape of the single die aperture cause the formation of an oval cavity (20) within the extruded protective cover material. The oval cavity has major and central axes (A 1 , A C ) and surrounds the at least one optical fiber. The strength members lie along the cavity major axis. Tensioning the strength members during extrusion and then releasing the tension causes the drop cable length to be reduced. This gives rise to an excess fiber length, which adopts a serpentine configuration substantially in a plane (PF) defined by the major and central axes (A1, A2) of the oval cavity.
摘要翻译：公开了一种形成低成本液滴电缆（10）的方法。该方法包括提供挤出温度为140℃‰TE‰×160℃的保护性覆盖材料（352）。保护性覆盖材料通过具有限定电缆的细长横截面形状的单个孔（424）的管芯（420）挤出。挤出工艺涉及在至少一根光纤（50）的任一侧覆盖第一和第二强度构件（30）。可挤压保护性覆盖材料的低温与单模孔的细长形状的组合导致在挤出的保护性覆盖材料内形成椭圆形空腔（20）。椭圆形腔体具有主轴和中心轴线（A 1，A C）并围绕至少一根光纤。强度构件位于空腔长轴上。在挤出过程中拉紧强度部件，然后释放张力会导致牵引电缆的长度减小。这产生了过多的纤维长度，其采用基本上在由椭圆形腔的主轴和中心轴（A1，A2）限定的平面（PF）中的蛇形构造。
