Using an optical medium provides the following
advantages:
An example for an interface to an optical connector is
given in Fig.40. In most cases a transistor is required to
amplify the TX-output current.

Bus nodes are galvanically decoupled.
Optical cable features very high noise immunity.
No noise emission by the bus cable.

Thus more optical power is provided to compensate for
losses in the optical connectors and the optical star. The
P8xC592 features an on-chip
output so only a capacitor is required for the receiver part.
Two optical fibres are used to connect the bus nodes. The
TX-fibre transfers the output signal of the CAN-controller
to the optical star. The optical star transfers the TX-fibre
input signal over to all the RX-fibres. The RX-fibres
transfer the resulting optical signal over to the receivers of
all the bus nodes.
