I don't know Doc, if the line is broke iside insulation it may still show the light. How do you judge the light intensity, I don't know.
As far a PLC, didn't know they used them with fiber optics, but an PLC is not that complicated as long as you understand ladder diagrams, and understand relay logic.
On a PLC you connect all the controls (input/output) to (incoming/outgoing) terminals on the PLC terminal panel. Then PLC controls all {relay} operations. Learning the symbols and their functions are what matter. Much better than relay panels, especially if you make a mistake, quick to fix. Thats what I remember, hope it helps!
