21、s Fibre opticconnector proof test with static load Singlemode and multimode 1 Scope This part of IEC 61300 describes a test to quantitatively assess the capability of connector terminated patchcord cable assemblies to withstand static loads without uncoupling of the connector, physical damage to the
22、 assembly or permanent degradation of optical performance. This test is intended to apply to terminated reinforced jacketed cable of any diameter, both singlemode and multimode. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、sembly at 0 (straight pull) and at 90(side pull) to the connector axis and held for a fixed time, while the mated connector assembly is held fixed by the adapter. The sample is examined and measured for attenuation and return loss before and after each load is applied. 4 Apparatus The apparatus for
27、this testis shown in Figure 1. The patchcord tension is applied with weights through a capstan. The patchcord is flexed at the point of entrance to the connector plug by rotating the test arm. The position of the connector assembly along the test arm should be adjusted so that, when the arm is at 90
28、, the centerline along which the cable hangs passes through the test point. The fixture is to be designed to allow the capstan to be rotated about the axis of the section of cable under tension.
