There is provided an optical communication apparatus, which is provided with
a light emitting device that emits a transmission light signal modulated with transmission
data, an optical fiber, and a deflecting system that is located between the light
emitting device and the optical fiber so as to move a position of the transmission
light signal on an entrance surface of the optical fiber. The optical communication
apparatus is further provided with a feedback control system that controls the
deflecting system so as to move the position of the transmission light signal to
a center of a core of the optical fiber based on intensity of a portion of the
transmission light signal.
