Abstract

The invention discloses a vehicle-mounted optical fiber switch supporting a hybrid topological structure. The vehicle-mounted optical fiber switch comprises a switch body and an optical fiber coupler, the switch body is provided with a plurality of optical ports, and each optical port is connected with a large-bandwidth device or a plurality of small-bandwidth devices according to the bandwidth required by each device in the vehicle; the plurality of small-bandwidth devices are connected to the same optical port through the optical fiber coupler; each device in the vehicle and the switch body form a hybrid topological structure network; the switch body is used for configuring the working mode of the optical port to be a point-to-point working mode or a point-to-multipoint working mode and controlling data interaction between devices in the vehicle. According to the invention, each optical port can support point-to-point full duplex connection or point-to-multipoint passive coupling connection, and respectively support switching type topological structure connection and bus type topological structure connection between devices; the bandwidth utilization efficiency of the switch can be improved, the number of optical ports is reduced, and volume consumption is reduced.
