Question

In the case of loose-buffered fiber, the buffer material may or may not be attachedto the device housing and used as a strength member. For devices where the buffermaterial is not used as a strength member, less stressful conditions than those listedin Table 4-3 apply for the side-pull and cable retention tests. (In particular, the testconditions listed for devices with coated and tight-buffered fiber pigtails applyinstead.) In addition, it should be noted that loose-buffered cable generally includesPVC or Hytrel tubing that will stretch and allow the fiber to take up the load. Thistubing is typically used to improve the abrasion resistance of the cable, not thetensile strength.

Answer 1

在松散缓冲光纤的情况下，缓冲材料可能会或可能不attachedto装置的壳体和作为强度构件。设备不作为buffermaterial用强度构件，侧拉电缆固定测试压力较小的适用条件比那些listedin的表4-3。 （特别是，testconditions列出了涂层和紧缓冲光纤尾纤applyinstead的设备）。此外，应该指出的是，宽松的缓冲电缆一般includesPVC或Hytrel管线，将伸展，并允许光纤的负载。 thistubing通常用于提高耐磨损性的电缆，不thetensile强度。

Answer 2

对于松散缓冲纤维缓冲材料可能会或可能不会在设备住房和用作强度成员。对设备buffermaterial不是用作强度成员,少压力的条件比listedin表4 - 3申请侧拉和电缆保留测试。(特别是对设备testconditions上市与涂层和紧缓冲纤维辫子applyinstead。)此外,应该指出的是,宽松的缓冲电缆一般includesPV

Answer 3

对于松散缓冲纤维缓冲材料可能会或可能不会在设备住房和用作强度成员。对于设备的缓冲材料不是用作强度成员,少压力的条件比列于表4 - 3申请侧拉和电缆保留测试。(特别是,测试条件与涂布设备上市和紧缓冲纤维辫子应用相反。)此外,应该指出的是,宽松的缓冲电缆一般包括PVC或为什么会伸展和灵油管,使纤维带负载。这个油管通常用于提高耐磨性的电缆,而不是不同的力量。
