43 43 Reduced Installation Costs Reduced costs due to the replacement of hundreds or even thousands control cables with a limited number of fiber optic cables Reduced costs due to the replacement of the wiring of hundreds of copper wires to the panels terminal blocks and then from the terminal blocks to the relay terminals with the plugging in of a few pairs of fiber cables Reduced costs due to the requirements for testing of all hard wired interfaces versus the testing of the GOOSE messages based on advanced software tools
