The MOST network is an optical network where all control modules are connected in a ring.
All messages within the MOST-net pass in one and the same direction from Infotainment Control Module (ICM) to Accessory USB Unit (AUU) (applies
to S80/V70/XC70) respective Remote digital audio receiver (RDAR)/Digital Audio Broadcast Module (DABM) (applies to XC60).
In a fiber optic network, light pulses are transmitted instead of electrical signals. The light pulses are interpreted in the same way as the electrical signals
on the CAN network.
The MOST network uses the master-slave concept. This means that a master control module, infotainment control module (ICM) has overall control of
communication on the MOST network.
The fiber optic cable is made of plastic. Communication is using red light on a wavelength of 650 Nm.
The optical connector
Each control module in the MOST network has an optical connector which consists of two diodes, a sender diode and a receiver diode. These transmit
