An optical transmitter includes: a light emitting part that emits light; and a lens that condenses the light emitted from the light emitting part. Further, the optical transmitter includes 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. Furthermore, the coefficient of the correlation between the distribution of the intensity of the light in the light emitting part and the distribution of the 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.

Optical transmitter and optical transmission system

A communication system includes a vehicle exterior antenna, an electro-optic converter, and a multimode optical fiber. The vehicle exterior antenna transmits and receives an electric signal to and from a cloud system in the exterior of a vehicle. The electro-optic converter is connected to the vehicle exterior antenna and converts an electric signal received by the vehicle exterior antenna into an optical signal. The multimode optical fiber has a plurality of propagation modes for propagation of optical signals and connects the electro-optic converter and an on-vehicle device (an opto-electric converter, an on-vehicle router, and the like) in the interior of the vehicle.

Communication system

An optical connector is provided with a first housing, a first optical fiber accommodated in the first housing, a second housing to which the first housing fits, and a second optical fiber accommodated in the second housing. An end face of the first optical fiber abuts on an end face of the second optical fiber due to fitting the first housing to the second housing so that the first optical fiber and the second optical fiber are optically connected.
