25、f of fibre optic devices. The intention is to simulate the number of flexing cycles which would typically be experienced during service life. This test is applied to both single fibre cable and multiple fibre cable. 2 Normative references The following documents, in whole or in part, are normatively

30、he attached cable and in the case of ribbon cable, parallel to the width of the ribbon. This causes flexing of the strain relief and cable close to the DUT. During the flexing, a tensile force, but no torque, is applied. 4 Apparatus 4.1 General The apparatus for testing and the flexing patterns invo

If the devi

34、ce is a fibre optic connector, an adaptor or a receptacle may be used as a mounting fixture. The fixture shall not distort the DUT. The fixture shall allow the DUT to be connected to monitoring equipment. 4.5 Flex test machine or jig A machine or jig that can rotate the DUT 90ofrom a straight positi

35、on while applying a load to the fibre or cable. 5 Procedure 5.1 Preparation of specimens Prepare and clean the specimen in accordance with the manufacturers instructions. Visually check that the attachment of the cable to the fibre optic device is not damaged in accordance with IEC 61300-3-1. Fibre

36、length from the flex point to the weight: 25 cm 5 cm. Fibre length is measured from the point of flexing to the point of application of the load. 5.2 Preconditioning Pre-condition the specimen and all equipment for 2 h at the standard test conditions as defined in IEC 61300-1, unless otherwise speci

37、fied in the relevant specification. 5.3 Initial measurements Complete initial examinations and measurements on the specimen as required by the relevant specification. 5.4 Conditioning Install the DUT on the apparatus. Measure the attenuation of the DUT with the flexing arm in a vertical position in

38、accordance with IEC 61300-3-4. Apply the specified tensile load and apply the specified number of flexes. Use gentle rotational movements, not exceeding 20 cycles/min. The dwell at each extreme shall be not greater than 5 s. Measure the change in attenuation during test in accordance with IEC 61300-

39、3-3. Stop the flexing with the flexing arm in vertical position. Remove the tensile force. BS EN 61300-2-44:2013 8 61300-2-44 IEC:2013(E) 5.5 Recovery Allow the DUT to remain under standard test conditions for 2 h, as defined in IEC 61300-1, unless otherwise specified in the relevant specification.

40、Clean the DUT in accordance with the manufacturers instructions. 5.6 Final measurements Remove the DUT from the apparatus and make final measurements, as defined by the relevant specification, to ensure that there is no permanent damage to the DUT. The results of the final measurement shall be withi

41、n the limit established in the relevant specification. Visually check that the attachment of the cable to the fibre optic DUT is not damaged in accordance with IEC 61300-3-1. 6 Severity Severity is specified by the magnitude of tensile force and the number of cycles +90 to 90.
