Fibre Optic Cable Repair: Information

The components in the infotainment system are part of an optical network, known as the MOST network. (Media Oriented System Transportation). The network comprises fiber optics. Special connectors are used in the MOST network for fiber optics and MOST control modules, i. e. control modules that are connected to the MOST network.

Data is transmitted via the fiber optics, for example music, in the form of light signals. The MOST network is a ring which must be unbroken for it to work. If a fiber optic breaks or a connector is not connected, none of the infotainment system components will work. The ends of the fibers must also be free of dirt so that the light is not obstructed.

A fiber requires a larger bend radius than a copper cable. The bend radius must not be less than 25 mm  . If the fiber bends too much, not enough light will be let through.
