31、asic test and measurement procedures Part 3-35: Examinations and measurements Fibre optic connector endface visual and automated inspection 3 Apparatus 3.1 Source (S) The source unit consists of an optical emitter, the means to connect to it and the associated drive electronics. A tunable light sour
32、ce (TLS) in which a specific output wavelength can be tuned may be chosen as the optical emitter. A TLS may consist of a tunable LD and an optical amplifier, or be a fibre ring laser in order to get an efficient power to test. Generally, the power and stability requirements of a test will necessitat
33、e that the means to connect to the optical emitter be a fibre pigtail. It shall be stable in output power and wavelength/frequency over the measurement period. For DWDM devices, the frequency uncertainty (instead of the wavelength uncertainty) shall be less than half of the channel bandwidth. Unless
34、 otherwise stated in the relevant specification, the source shall have the following characteristics: a) Centre wavelength uncertainty including stability: BS EN 61300-2-14:2013 6 61300-2-14 IEC:2012 nominal centre wavelength 5 nm (for WWDM and CWDM devices); b) Centre frequency uncertainty: nominal
35、 centre frequency 6,3 GHz (for DWDM devices of 25 GHz channel bandwidth); nominal centre frequency 12,5 GHz (for DWDM devices of 50 GHz channel bandwidth); nominal centre frequency 25 GHz (for DWDM devices of 100 GHz channel bandwidth). c) Output power uncertainty and stability: nominal output power
36、 0,05 dB. 3.2 Optical detector (D) The optical detector unit is an optical power meter and consists of an optical detector, the means to connect to it and the associated electronics. The detectors shall have sufficient dynamic range to make the necessary measurements and shall be linear over the mea
37、surement range. The detectors shall be stable over the measurement period and shall have an operational wavelength range consistent with the DUT. The connection to the detectors shall be an adaptor that accepts a connector plug of the appropriate design. The detectors shall be capable of capturing a
38、ll light emitted by the connector plug. Unless otherwise stated in the relevant specification, the detectors shall have the following characteristics: linearity: 0,1 dB; uncertainty including polarization dependency: 0,05 dB; resolution: 0,01 dB. 3.3 Environmental chamber The test set-up shall inclu
39、de an environmental chamber capable of producing and maintaining the specified temperature and/or humidity. 3.4 Data acquisition system (DAS) Recording of the optical power readings at the optical detector may be done either manually or automatically. Appropriate DAS shall be used where measurements
40、 are performed automatically. 3.5 Branching device (BD) The splitting ratio of the branching device shall be stable over the optical powers and wavelengths chosen for the test. It shall also be insensitive to polarization. The branching devices shall be stable during the test. The splitting ratio of
41、 1:99 for branching devices is recommended in order to input high power to the DUT and low power to the optical detector. 3.6 Temporary joints (TJ) These are typically used in connecting the device under test to the test apparatus. Generally, the optical power and stability requirements of a test wi
42、ll necessitate that the temporary joints be fusion splices. 3.7 Safety devices All necessary safety devices, including laser safety glasses, signs and other safety materials, shall be provided in order to protect individuals from possible hazards during testing. 3.8 Test set-up For two-port optical
43、components, a typical layout for the test apparatus is shown in Figure 1. BS EN 61300-2-14:201361300-2-14 IEC:2012 7 This test procedure involves the use of optical powers, which constitute a potential ocular and skin hazard to test personnel. All necessary safety procedures shall be adopted in acco
44、rdance with IEC 60825-1. In particular, the DUT shall be unpowered (that is, with no power propagating in the fibre) when conducting a visual examination. Optical connectors shall not be used. Fusion splices shall be used for all connecting points as described in 3.6. Environmental chamber S BD BD D
45、UT Metal doped fibre (Termination) TJ TJ D1 D3 D2 DAS IEC 2024/12 Figure 1 Optical power test set-up For multiport devices such as branching devices, all combinations of input and output ports shall be tested, unless otherwise stated in the relevant specification. For WDM devices, multi-wavelength s
46、hall be input at the same time according to the application. Clause A.1 describes an example of the test set-up for WDM devices. To minimize test equipments, the DUTs can be connected as a series. Clause A.2 describes an example of the test set-up for a series connection of DUTs. 4 Procedure 4.1 Pre
47、conditioning The chosen test samples shall be representative of a standard product. Prepare and clean the DUTs according to the manufacturers instructions. Visual examination shall be undertaken in accordance with IEC 61300-3-1 and IEC 61300-3-35. Debris or the presence of contamination is one of th
48、e primary causes of failure in high optical power connector applications. Precondition the DUTs for 2 h at the standard atmospheric conditions as defined in IEC 61300-1, unless otherwise specified in the relevant specification. 4.2 Initial examinations and measurements Complete initial examinations
49、and measurements on the DUTs as required by the relevant specification. The results of the initial measurement shall be within the limit established in the relevant specification. BS EN 61300-2-14:2013 8 61300-2-14 IEC:2012 4.3 Conditioning 4.3.1 Set the chamber and the DUT to the standard atmospheric conditions. Place the DUT in the chamber in its normal operating position.
