A fiber optic tester ( 10 ) broadly comprises a testing unit ( 16 ) to take measurements across two test points ( 27 ), a processing unit ( 18 ) to locate faults by analyzing the measurements, a switching unit ( 20 ) that can connect termination points ( 13 ) of a electrical circuit ( 12 ) to the test points ( 27 ) in a sequence controlled by the processing unit ( 18 ), and a fiber unit ( 22 ) to test a optical circuit ( 14 ). The tester ( 10 ) may also include an electrical harness ( 24 ) or an optical harness to connect the electrical circuit ( 12 ) to the switching unit ( 20 ) or the optical circuit ( 14 ) to the fiber unit ( 22 ). The processing unit ( 18 ) is preferably programed with interconnection information of the circuits ( 12,14 ) and internal characteristics of the tester ( 10 ). Using the interconnection information and the internal characteristics, the processing unit ( 18 ) may accurately detect faults within the circuits ( 12,14 ).
