Hi Leo. Many years ago, my phone line took a lightning strike, and for all
practical purposes, it vaporized my computer. I presently have a mirror raid
configuration with Win 7 X64 professional. I have FiOS service, everything
hard-wired, not wireless. It is installed with the FiOS cable from the utility
pole into my house where it is connected into the multiplexer/ONT (both
terms being used by the installer) and coax cable from that to the FiOS
router/modem, and ethernet to the computer. Question: With this FiOS setup, is
there any cause for concern about another lightning hit? I am not concerned
about the electric power supply line being hit by lightning: that is already
protected. It also has a constant voltage transformer in the computer and
peripherals circuits to prevent low voltage. Thanks.
FiOS Fiber Optic Cable
The “O” in FiOS stands for “optical.” One of the assumptions that people often make is that because it is an optical-based service, that the connection into their house is in fact is being made over fiber optic cable.
Sometimes, it is. But as I learned awhile back, more frequently, it’s not.
The fiber that it refers to may in fact only go as far as the street.
The connection between the street and your home (and obviously the rest of your computers) may in fact still be copper. It may in fact be wired.
Electric wires and lightning
What that means is that, ultimately, if you’re in a lightning strike prone area then, yes, there’s an electrical wire hanging outside your house connected to your computers… that could potentially take a lightning hit and transmit the electrical energy from that lightning hit upstream.
At some point, I would hope that the FiOS equipment installed by your installer will actually be set up in such a way to be able to protect you from that. I’d want to confirm that with the installer for sure. But ultimately from our perspective, looking at it from the inside of the house, yea, you’ve probably got wires.
You probably have something that you want to protect yourself from, if this is in fact a lightning strike prone area in which you’re living.
I, for example, here in the Pacific Northwest, (at least where I live) just don’t get lightning strikes all that often. Certainly nowhere near the house, so it’s not something I would be concerned about. But in other areas of the country (or other areas of the planet), lightning is significantly more frequent, more common, and can cause more problems.
I would absolutely look at protecting yourself from it.
