Optical Signal Transmitting Device and Optical Signal Communication Device

According to an embodiment, the optical signal transmitting device includes an optical source unit comprising at least one light source element and a driving unit that controls the operation of the light source element to output optical signals. The driving unit generates the optical signal by dividing it into a first frame including a first data code and a first start code inserted at the starting point of the first data code, and a second frame including a second data code and a second start c
