The combinations of loads and angles to be applied at a rate of 5 N/s are those designated in the relevant specification. If these are not specified, the preferred loads and angles g
44、iven in Table 1 may be used. For small form factor connectors the preferred loads at the 90 and 135 tests are 2/3 those specified in Table 1. All optical measurements are made at singlemode 1 310 nm and 1 550 nm wavelengths and multimode 850 nm and 1 300 nm wavelengths. Optional: singlemode at 1 625
45、 nm, or as specified for the appropriate technology (for example, multimode at 650 nm). 5.2 Preparation of specimen Prepare and clean specimen in accordance with the manufacturers instructions. 5.3 Preconditioning Pre-condition the specimen for 2 h at the standard test conditions as defined in IEC 6
46、1300-1, unless otherwise specified in the relevant specification. 5.4 Initial measurements Complete initial examinations and measurements on the specimen as required by the relevant specification. 5.5 Test method 5.5.1 Measure attenuation and return loss as described in IEC 61300-3-6 and 61300-3-34
47、respectively. 5.5.2 Mount the sample in the apparatus shown in Figure 1. 5.5.3 Apply the combination of loads and angles as specified in the relevant specification beginning with 0 progressing from lowest to highest load for the appropriate media type, then repeat in order for the other angles. At e
48、ach combination of load and angle, after equilibrium is reached, measure attenuation and return loss during the test, record whether or not the connector uncouples, record whether or not damage occurs to the assembly, and, if so, record a description of the damage in accordance with IEC 61300-3-1.
