28、fibre optic connector ferrules. The precision hole aligns and positions the optical fibre inside the ferrule. The procedure described here uses the “GO“ and “NO-GO“ gauging technique. 3.2 General description The most commonly used inspection method for the inside diameter is the GO and NO-GO pin gau

29、ging technique. Due to the very small inside diameters of the connector ferrules for commonly used single mode and multimode ferrules, accurate direct measurement is difficult to achieve. One technique is the direct measurement of the inside diameter of a ferrule precision alignment hole. This can b

30、e carried out either by projecting the ferrule hole using a projection optical microscope or by using an imaging and digitizing system to measure the bore diameter. Thesr techniques tend to suffer from inaccuracy in determining the inside edges of a precision hole. Thus, the use of “pin gauges“ beca

31、me the most common method for determining the inside diameter of a ferrule manufactured to specified dimensional limits.

41、 diameter of fibre optic connector ferrules 4.1 Purpose The purpose of these procedures is to inspect and measure the outside diameter of fibre optic connector ferrules. The procedures described here use the ring GO and NO-GO gauging technique or contact and non-contact micrometer and laser diameter

42、 measurement techniques. 4.2 General description One method used to inspect the diameter of fibre optic connector ferrules is the ring GO and NO-GO gauging technique. The ferrule diameter can also be measured directly by using other suitable techniques. Conformity of the outside diameter of fibre op
