OPTICAL NETWORKS AND METHODS FOR USE IN AUTOMOBILES AND OTHER MOBILE VEHICLES

摘要

A vehicle is equipped with a network that permits multiple units to communicate with each other over a common optical bus. The optical bus is bi-directional and couplers direct optical signals that travel in both directions along the bus toward the various units connected to the bus. These couplers also direct optical signals from each unit onto the bus in both directions. The units may form part of one or more systems, such as an entertainment system, engine system, or data and communication system. The optical networks are immune to electromagnetic noise that may be generated within the vehicle and significantly reduce the amount of cabling compared to conventional electrical networks. The optical network can accommodate large numbers of units and systems by employing amplifiers dispersed throughout the network. The amplifiers compensate for splitting losses associated with the couplers and may be located along the bus or within the couplers.
