1. An optical transmitter comprising:
a light emitting part that emits light;
a lens that condenses the light emitted from the light emitting part; and
a multimode optical fiber that is optically coupled to the lens at one end and on which the light that is condensed by the lens is incident, wherein
a coefficient of a correlation between a distribution of an intensity of the light in the light emitting part and a distribution of an intensity of return light to the light emitting part, when the light is emitted from the light emitting part, is set to 0.5 or less.
