11. Communication

The protection IEDs are connected to the fibre-
optic communication bus directly or via bus
connection modules and gateways. The bus
connection module converts the IED's
electrical signals to optical signals for the
communication bus and, vice versa, the
communication bus' optical signals to
electrical signals for the IED.
