Abstract: An optical test device, in combination with a removable connector adapter, is provided. A method of testing an optical fiber is also provided. The test device comprises a test port configured to interface with optical-fiber cables having a given number of optical fibers. The connector adapter comprises a device connector adapted to connect to test port; and a fiber-under-test (FUT) connector adapted connect to an optical-fiber cable, such as a test cord connectable to the FUT. The FUT connector is configured to interface with optical-fiber cables having a number of fibers that is different from the number of fibers of the test port. The optical test device comprises a processing unit configurable to adjust the tests to be conducted based on the connector adapter detected, and to adapt the user interfaces and test parameters accordingly.
