A direct strike?  Don't think there's anything that will really protect
against that.

So even though you might have fiber coming in, remember that both the power grid and copper network cables are conductors and can make the lightning strike jump between devices. So the OP of this thread is right in wanting to protect both the network cables and power cables.

PS. I don't have more details about this specific case.
