Copper media is generally used for "inside-the-box" and other applications
much shorter than 30 meters. For box-to-box and longer distances, fiber
optic media is used which is inherently EMI,ESD, and RFI proof.

Wouldn't this cause nasty galvanic currents through the shield if the two
pieces of equipment, attached by the cable with the DB9s, were, say, on two
different phases of a three phase power feed to a building.

Am I missing something?
