Harry, The Brickwall website explains their technology versus MOV. An MOV is a little component about the size of a nickel that absorbs a fixed amount of surge current and then stops working or explodes.
The Optilator converts the telephone signal from electrical to fiber optic and then back again to electrical.. I think the guy who invented it is in Florida, real thunderstorm country. Just use Google to find it. To my knowledge, none of the computer brand surge suppressors use anything except one or two little MOV's. For networked computers, pay attention to what the Brick Wall website says about diverting surge to ground and contaminating data lines. They are referenced to the same ground plane. If you need a UPS, just plug it in to the Brick Wall. I think the 2 outlet unit costs $159, and I have a power strip plugged into it to handle all of the computer equipment.
