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.
