10 Method E6: Repeated bending10.1 ObjectThe purpose of this test is to determine the ability of an optical fibre cable to withstand repeated bending.Repeated bending of connectorized optical fibre cable involves testing as a unit, testing both the capabilities of the cable and the connector. This testing is defined by IEC 61300-2-44. Refer to that…
5 Apparatus 5.1 Impact surface, which should be either: a) a plane inclined to the vertical at 10° ± 1° (for the inclined plane test), or b) a plane vertical to within 1° (for the horizontal or pendulum test). The dimensions of the impact surface shall be greater than those of the impacting face, or…
