Abstract: A vehicle-mounted apparatus is a vehicle-mounted apparatus mounted in a vehicle, and includes a measuring unit that measures characteristics of a transmission line in a vehicle-mounted network mounted in the vehicle, and an identifying unit that identifies the transmission line based on the characteristics measured by the measuring unit.

Abstract: An in-vehicle device includes: a measurement unit configured to measure a characteristic of a transmission path in an in-vehicle network mounted to the vehicle; an acquisition unit configured to acquire deterioration information which is information regarding deterioration of the transmission path and which corresponds to the characteristic measured by the measurement unit; and a determination unit configured to determine a deterioration degree of the transmission path, based on the characteristic measured by the measurement unit and the deterioration information acquired by the acquisition unit.

Abstract: 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.
