ABSTRACT:
A communications connector tester for quickly and accurately analyzing communications connectors at production to determine whether the connectors are fit for use in certain communications applications is disclosed. Test signals at several discrete frequencies are sequentially inputted into pairs of conductors in the communications connector under test, and output signals are detected for the pairs under test. The output signals are compared to acceptable ranges for certain applications of the communications connector and the connector is passed or failed for certain applications based on the output signal values. Near-end crosstalk, far-end crosstalk, return loss, insertion loss, and other communications connector qualities may be measured using the present invention.
