Abstract: An optical fiber testing device (300) being plugged into a port at which optical signals including communication and test signals within different wavelength bands being received, comprises an optical connector (304) including a plug body surrounding a ferrule holding an optical fiber (301) and a reflector component (326) carried with the optical connector (304). The reflector component (326) is optically coupled to the rear of the optical fiber and reflects the test signal. A method for testing an optical fiber, comprises removably securing a reusable ruggedized optical fiber testing device to a ruggedized port of an optical fiber terminal to optically couple to an optical fiber under test, transmitting a test signal over the optical fiber under test, and using the reflector component to return the test signal over the optical fiber under test when receiving the test signal.
