Abstract

Method and apparatus for measuring both the contact force and ferrule length of a fiber optic connector and for measuring the length of an adapter versus the requirements of the TIA/EIA's specifications so that connector intermateability may be determined. The contact force and ferrule length measurement apparatus includes an adapter for holding the connector being tested in place, a gauge pin for detecting the spring force of the connector, a gauge force meter for measuring the force exerting on the gauge pin, and a micropositioner for aligning the gauge pin with the ferrule of the connector. Once the gauge pin and connector are aligned, the spring force is measured based on displacement of the position of the ferrule. The adapter length measurement apparatus includes two sets of test reference connector plugs, each electrically connected at one end to an ohmmeter, so as to form an electrical circuit. Adapter length measurements are made by inserting the free end of first one set and then the other set of each test connector plug into the adapter under test and then measuring the resistance on the ohmmeter. A high resistance with the set of longer reference plugs indicates the adapter is too long. Conversely, a low resistance with the set of shorter reference plugs indicates the adapter is too short.
