23、00-3-4, Fibre optic interconnecting devices and passive components Basic test and measurement procedures 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 lo
24、ss is measured. 4 Apparatus 4.1 Mounting fixture The mounting fixture is a vertical surface that 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 accommod
25、ating those devices where the input and output fibre cables are co-located on the same side of the 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 distan
26、ce from the end of the connector to the panel. 4.2 Panel The panel consists of a flat surface that is brought parallel to the mounting fixture to simulate a cabinet door closing on the installed device. 5 EN 61300-2-49:2007 To detector To optical source Mounting fixture Device under test PanelFibre
27、cable For example, 70 mm IEC 952/07 Figure 1 Example of the connector installation test 4.3 Optical source and detector The optical source and detector used to measure changes in attenuation shall comply with that specified in IEC 61300-3-4. See Table 1 for preferred wavelengths. Table 1 Preferred w
28、avelengths 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 under test shall be terminated with a suffi
29、cient 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 specification. Measure and record the atten
30、uation of the device under test. EN 61300-2-49:2007 6 5.3 Initial measurements Complete initial examinations and measurements 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
31、 mounted in a representative manner onto the mounting fixture (see Figure 1). The jumper cable that exits from the device 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 tha
32、t the fixturing has not affected the cables attenuation. 5.6 Applying the panel Bring the panel to a position that is parallel 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 th
33、e specimen shall be measured with the panel in position, as described in IEC 61300-3-4, unless otherwise specified in the 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 int
34、erfaces in the device. 5.8 Final measurements and examinations On completion of the test, remove the panel and make a final 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, visua
35、lly 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 damaged parts or accessories; breaking or damage to the cable jacket, seals, strain relief, or fibres; displaced, bent, or broken parts; 6
36、 Severity The severity of the test is dependent upon the distance of the panel from the samples mounting position and the length of the connector. 7 EN 61300-2-49:2007 7 Details to be specified The following details, as applicable, shall be specified in the relevant specification: distance of the pa
37、nel to the mounting device/fixture; initial examinations, measurements and performance requirements; examinations, measurements and performance requirements during test; final examinations, measurements and performance requirements; deviations from this test method; additional pass/fail criteria.
