[6] Configuration combining local and long distance distribution
In the basic configuration, if a specific controller is located a long distance away, or if there is a high voltage power source or noise generating source near the network, divide the network into two segments and connect an optical cable between the two segments. This will allow you to construct a combined local and long distance network with good noise immunity.
