Optical Bus
WARNING: This page does not describe the selected car, but rather 59 other vehicles, including the 2009 BMW M5, 2009 BMW 650i, 2009 BMW 550i, 2008 BMW M5, and 2008 BMW 760Li. However, it is still accessible from the selected car via links, so may be relevant.
The MOST bus is a plastic optical waveguide. The MOST bus is coded in green in the E65.
The light wavelength is 650 Nm (red light). The MOST bus requires the following converter components:
- Optical transmitter
- Optical receiver
Each control unit of the MOST framework contains a transmitter and a receiver. The transmitter and receiver have been developed by BMW. The low closed circuit (rest) current properties of the transmitter and receiver enable optical wake-up by the MOST bus.
