Abstract

An apparatus is disclosed for testing the integrity of an optical fiber (23) from a single end of the fiber. A test light source (34) with a wavelength that is different from the primary light source (14) is directed into one end of the optical fiber (23). A spectrally selective dichroic material (32) is attached to the other end of the optical fiber (23). This material (32) transmits light of the wavelength of the primary light source (14) and reflects light of the wavelength of the test light source (34). A break or discontinuity in the optical fiber (23) can be detected by an attenuation in a pulse of light from the test light source (34) after it is transmitted though the optical fiber (23) and reflected back out of the optical fiber (23) by the dichroic material (32). This system can detect breaks or discontinuities in the optical fiber (23) with a high degree of resolution.
