22、FO-6.3, Subcommittee on Fiber Optic Interconnecting Devices.) This FOTP is part of the series of test procedures included within Recommended Standard EIMIA- 455. I Introduction 1.1 Intent The intent of this procedure is to determine the inside diameter of the ferrule hole in an optical fiber connect
23、or ferrule. 1.2 Accuracy and precision The precision of the method is affected by the incremental differences in the outer diameters of the calibrated wire set used for the measurement. The accuracy of the method is controlled by the calibration of the calibrated wire set. 1.3 Applications This proc
24、edure is applicable to all optical fiber connectors. 2 Applicable documents Test or inspection requirements may include, but are not limited to, the following references: EIMIA-455-A Standad Test Procedures for Fiber optic Fibers, Cables, Transducers, Sensors, Connecting and Terminating Devices, and

26、) Use a wire holder to hold the calibrated wires during the measurement. 3.3 Calibrated wire set Use a calibrated wire set with outside diameters that encompass the ferrule inside diameter specified in the Detail Specification that meets the following requirements: a. b. C. Unless otherwise specifie
27、d, use wires that have known outside diameters (traceable to NIST) with a tolerance of -0.0, W.25 pm. Unless otherwise specified, use a wire set with maximum differences in the diameters of consecutive wires of 2 percent of the wire diameter. For single-mode ferrules, use a wire set that includes at
28、 least one wire with an outside diameter equal to the ferrule inside diameter specified in the Detail Specification. For multimode ferrules, use a wire set that includes wires having outer diameters equal to the maximum and minimum sizes specxfied in the Detail Specification. If a wire in the set is
29、 used for more than one test specimen, periodically verify the outer diameter calibration of the wire. d. e. 4 Sampling and specimens Unless otherwise specified in the Detail Specification, use an optical fiber connector ferrule for the test specimen. The specimen may be part of an optical fiber con
30、nector at the time of measurement. Keep the specimen free from dirt or dust with a front surface polished sufficiently to allow delineation of the boundaries of the hole. NOTE: Always clean the specimen at some time before performing this test procedure. 2 - STD=EIA TIA-455-134-ENGL 1997 3234b00 058

32、rule specimen in the optical fiber connector or ferrule holder. 5.3 Choose one wire of the calibrated wire set (the smallest wire is recommended). If applicable, place the wire in the calibrated wire holder. Insert the wire into the ferrule until it extends completely through the ferrule from one en
33、d to the other. 5.4 Remove the wire and repeat the procedure for the rest of the remaining wires (it is recommended that the smallest remaining wire be used each time) until all of the wires have been inserted or until it is not possible to completely insert a wire into the ferrule. 6 Calculations o
34、r interpretation of results The connector ferrule inside diameter reported is the diameter of the largest wire that can be passed completely through the connector ferrule. 7 Documentation 7.1 All applications Report the following information for each test: 7.1 .I Date and title of the test. 7.1.2 Id
