25、cedures Part 3-4: Measurements Attenuation 3 General description The specimen is mounted into the test apparatus as shown in Figure 1. A panel is brought parallel to the mounting fixture and change in loss is measured. 4 Apparatus 4.1 Mounting fixture The mounting fixture is a vertical surface that
26、consists of a means to hold the device under test in a stable and representative manner. For connectors the mounting fixture will incorporate an adaptor. The mounting fixture shall be capable of accommodating those devices where the input and output fibre cables are co-located on the same side of th
27、e device. For connectors, where an adapter is used to connect two connectors, if there is more than one way to mount the adapter in the fixture, the adapter should be mounted so as to maximize the distance from the end of the connector to the panel. 4.2 Panel The panel consists of a flat surface tha
28、t is brought parallel to the mounting fixture to simulate a cabinet door closing on the installed device.

See Table 1 for
30、preferred wavelengths. Table 1 Preferred wavelengths Singlemode 1 310 nm and 1 550 nm, optional 1 625 nm Multimode 850 nm and 1300 nm 5 Procedure 5.1 Preparation of specimens Prepare the specimens according to the manufacturers instructions or as specified in the relevant specification. The device u
31、nder 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 conditions as given in IEC 61300-1, unless otherwise specified in the relevant s
32、pecification. Measure and record the attenuation of the device under test.

33、ments on the specimen as required by the relevant specification. 5.4 Conditioning Clean the connector according to the manufacturers instructions. The body of the specimen shall be mounted in a representative manner onto the mounting fixture (see Figure 1). The jumper cable that exits from the devic
34、e under test is to be dressed so that about one metre of cable is supported by the end of the connector boot. 5.5 Measuring the attenuation Re-measure the attenuation to ensure that the fixturing has not affected the cables attenuation. 5.6 Applying the panel Bring the panel to a position that is pa
35、rallel to the mounting fixture surface and at a distance from the mounting panel as illustrated in Figure 1. 5.7 Monitoring attenuation with the panel applied The attenuation of the specimen shall be measured with the panel in position, as described in IEC 61300-3-4, unless otherwise specified in th
36、e relevant specification. Any deviation in the device attenuation from that measured in 5.5 shall be considered attributable to the cable/device interface, or to fibre-to-fibre interfaces in the device. 5.8 Final measurements and examinations On completion of the test, remove the panel and make a fi
37、nal attenuation measurement to ensure that there is no permanent damage to the device under test. 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 m
38、ay include, for example: broken, loose or damaged parts or accessories; breaking or damage to the cable jacket, seals, strain relief, or fibres; displaced, bent, or broken parts; 6 Severity The severity of the test is dependent upon the distance of the panel from the samples mounting position and th
39、e length of the connector.
