Fiber Optic Thunder/Lightning.

Lightning is light in the form of electricity, hence it's name. It can travel down a fibre optic cable and blow up your modem.

NOT.

And again you completely ignore the point. Need I post the sentence again so you will read it?

Fiber alone does not guarantee protection from potentially destructive transients. And again you argue what is irrelevant (and incorrect) only to argue. To subvert informed discussion with your emotions.
 
Fibre and Lightning

Hey guys I got fiber optic cables a couple of weeks ago. The guy who put it up for me said I must turn it off if there is thunder or lightning. Is that true? If u also have fibre do u do that?

All right everyone, I think I can help settle this issue.

The installer probably told you to unplug the CPE to protect against power surges via your power supply. Glass is less conductive than copper, so the fibre line itself won't be transmitting the current.

From personal experience, lightning can damage appliances and electrical devices if the current is conducted through the device's power supply. We unplug our modem and router religiously for every single thunderstorm (which is a serious pain when you live on the Highveld in summer), yet a lightning strike still took out several of our larger appliances in November 2015.

A bolt hit a utilities pole on the pavement next to our property. Since it had been raining heavily for more than an hour before that, there was enough water everywhere for at least some of the discharge to be conducted into our electric fence, which then took out several appliances that were still plugged in at that point in time. We definitely know that the current had not gone through the phone line, because that was unplugged and the modem was untouched afterwards.

So, yes, if you want to protect your CPE during thunderstorms, I would recommend either unplugging its power supply during the storm, or using a UPS to power it. Purely as a cautionary measure to protect you from power line surges.

Nobody said fiber equipment was protected 100 years ago. All equipment was protected even 100 years ago. At least this time you have the decency to not waste bandwidth with profanity. Now please read what is written; not what you want to pervert so as to argue.

Unfortunately, not all equipment was protected 100 years ago. Jo'burg Municipality was complaining the 1920s that high voltage transmission systems in some of the other municipalities on the Rand were prone to power outages resulted from lightning strikes. It's the justification that they used to not take power from Escom.

Fibre is light. Lightning is light. Hmmm ... how much data can travel via lightning :erm:

Lightning is not light. Lightning is an electrical discharge through air. The reason why we can see it is because the high voltage causes the air in its immediate vicinity to heat up, which causes the atoms and/or molecules in the air to emit photons.

Then why is it called lightning and not photoning?
