Abstract: An apparatus and method for driving an optical source for an optical fiber link monitoring apparatus. The apparatus for driving an optical source for an optical fiber link monitoring apparatus includes a laser part configured to output probe light that corresponds to a bipolar code probe signal; an optical receiver configured to convert reflected light, which has travelled back from an optical fiber link after transmission of the bipolar probe light, into an electrical signal; and a direct-current (DC) canceller configured to remove a DC offset component from the electrical signal generated by the optical receiver.

Abstract: Disclosed is an optical fiber cable monitoring apparatus using a dual light source. The optical fiber cable monitoring apparatus includes: an optical transmitter configured to comprise a first light source and a second light source, which output light of different wavelengths, and to operate the first light source and the second light source to propagate first probe light and second probe light to an optical fiber cable; and an optical receiver configured to comprise a first light receiving module and a second light receiving module, each receiving first reflected light and second reflected light which are reflected from the optical fiber cable.
