Functionality MOST bus
The MOST bus is a serial bus system that transmits audio, video, voice and data signals in vehicles via fiber optic cables. Used globally by major car brands for multimedia applications, it relies on synchronous data communication. Care must be taken when handling fiber optic cables; they must not be kinked or overstretched, and the bending radius should not be less than 25 mm.
The transmission rate is 21.2 Mbit/s. In the event of a fault, such as a break in the fiber optic cable, a ring-break diagnosis system kicks in, using a separate electrical line to check the functionality of each control unit to determine the location of the break.
