24、 2-42: Tests Static side load for strain relief 1 Scope This part of IEC 61300 specifies a test to determine the influence of a side load applied to a cord assembled with a strain relief. The intention is to simulate a static load, due to a length of fibre cable, which would typically be experienced
25、 during service. Components should withstand side loads during optical transmission without degradation of the optical performance. Besides a boot, any feature that controls the bending radius of the fibre can be considered as strain relief. 2 Normative references The following documents, in whole o

29、: Examinations and measurements Attenuation 3 General description The specimen is inserted into the test apparatus as shown in Figure 1. A load, equivalent to several metres of cable, is applied to the cable attached to the device under test and any changes in optical attenuation are recorded during
30、 the specified period of the test. NOTE This test is applicable only to those passive optical components where the product design incorporates fibre cable pigtails. 4 Apparatus 4.1 Load generator The load generator consists of a mass and a means of clamping the mass to the cable. The clamping shall
31、not introduce micro- or macro-bending losses in the cable. BS EN 61300-2-42:2014 6 61300-2-42 IEC:2014 4.2 Holding fixture The holding fixture consists of a means to hold the device under test in a stable and representative manner. For connectors, the holding fixture shall incorporate an adaptor whe
32、re required. The holding fixture shall be capable of accommodating those devices where the input and output fibre cables are co-located on the same side of the device. 4.3 Optical source and detector The optical source and detector used to measure changes in attenuation shall comply with that specif
33、ied in IEC 61300-3-4. A device to record attenuation over time (X, t) should be used where the optical detector does not have the capability to monitor continuously (i.e. where the sample rate is 10/min). 5 Procedure 5.1 Preparation of specimens Prepare the specimens according to the manufacturers i
34、nstructions or as specified in the relevant specification. The device under test shall be terminated with a sufficient length of fibre cable to facilitate interfacing with the optical source and detector. 5.2 Pre-conditioning Pre-condition the device under test for 2 h at the standard test condition
35、s as given in IEC 61300-1, unless otherwise specified in the relevant specification. 5.3 Initial measurements Complete initial examinations and measurements on the specimen as required by the relevant specification. Measure and record the attenuation of the device under test. 5.4 Conditioning The bo
36、dy of the specimen shall be mounted in a representative manner onto the holding fixture (see Figure 1). The clamp to which the load can be applied shall be fastened to the cable in such a manner that the optical fibre or cable is not crushed. Unless otherwise specified, the point of load application
37、 shall be 20 cm to 30 cm from the end of the strain relief.

38、sure the attenuation Re-measure the attenuation to ensure that the fixturing and cable clamping have not affected the cables attenuation. 5.6 Apply cable load Gradually apply the specified load to the cable clamping fixture, being careful to avoid any sudden jerking or straining of the cable. Mainta
39、in the load for recommended duration (or as specified in the relevant specification). 5.7 Monitor attenuation The attenuation of the specimen shall be continuously monitored during the test, as described in IEC 61300-3-3, unless otherwise specified in the relevant specification. Any deviation in the
40、 device attenuation from that measured in 5.5 shall be considered attributable to the cable/device interface, or fibre-to-fibre interfaces in the device. If there are unacceptable changes in attenuation and it is questionable whether the cable itself may be at fault, a control test to determine cabl
41、e contribution should be performed in the same manner using a piece of cable and two cable clamps. 5.8 Recovery Allow the specimen to remain under standard test conditions for 2 h at the standard test conditions as given in IEC 61300-1, unless otherwise specified in the relevant specification. BS EN
42、 61300-2-42:2014 8 61300-2-42 IEC:2014 5.9 Final measurements and examinations On completion of the specified duration, remove all fixtures and make a final attenuation measurement to ensure that there is no permanent damage to the device under test. The results of the final measurement shall be wit
43、hin the limit established in the relevant specification. Remove the device from the mounting fixture and, unless otherwise specified, visually examine the specimen in accordance with IEC 61300-3-1. Check for evidence of any degradation in the specimen. This may include, for example: broken, loose or
44、 damaged parts or accessories; breaking or damage to the cable jacket, seals, strain relief, or fibres; displaced, bent, or broken parts. 5.10 Repeated testing Where required by the relevant specification, the test shall be repeated with the load applied in mutually perpendicular directions as permi
45、tted by the product design. For example, a product with a base plate extending beyond the fibre exit may prohibit loading in that direction. The number of mutually perpendicular directions employed shall be defined. 6 Severity The severity of the test is dependent upon the tensile load applied and t
46、he duration, as recommended in Table 1.
