An in-vehicle communication system includes: an optical coupler; a first in-vehicle device group composed of a plurality of in-vehicle devices connected to a first end of the optical coupler; and a second in-vehicle device group composed of a plurality of in-vehicle devices connected to a second end of the optical coupler. The in-vehicle devices in the first in-vehicle device group are communicable with the in-vehicle devices in the second in-vehicle device group via a common transmission path in the optical coupler. The in-vehicle devices in the second in-vehicle device group are communicable with the in-vehicle devices in the first in-vehicle device group via a common transmission path in the optical coupler.

Onboard communication system and communication method

A vehicle wiring system includes a plurality of functional units to be mounted in a vehicle, an optical transmission line that is wired between the functional units and configured to transmit an optical signal of the functional units, an optical coupler that is disposed in a partial section of the optical transmission line and constitutes a part of the optical transmission line, and a structural member that constitutes a part of the vehicle and is at least partially transparent. The optical coupler has an optical waveguide that passes through the structural member.

Vehicle wiring system and method of constructing vehicle wiring system

A vehicle wiring system includes a plurality of functional units to be mounted in a vehicle, an optical transmission line that is wired between the functional units and configured to transmit an optical signal of the functional units, an electric wire harness that is provided, in a partial section of the optical transmission line, together with the optical transmission line in a state of being integrated with the optical transmission line, and an optical coupler that is disposed in a portion of the optical transmission line other than the section and constitutes a part of the optical transmission line.

Vehicle wiring system, optical coupler, and method of constructing vehicle wiring system

An on-board communication system includes an optical coupler that includes multiple optical transmission lines, and multiple on-board devices that are capable of communicating with each other with the optical coupler interposed therebetween.
