There's also an interesting failure mode for fibers, known as "fiber fuse", which can happen when the power level is very high and an imperfection in the fiber causes the light to literally start burning it like a fuse:
Yeah, sorta. It's depressingly rare to find desktop motherboards with SFP ports, much less laptops. You end up converting back to copper anyway.
I have a fiber link in my home network, because I was sick of losing wifi routers every time a storm came through. I suspect the cable modem to be allowing badness to sneak in even past the grounding block (which doesn't ground the center pin, of course), so in addition to a UPS with a coax protector, I now also have the whole "outside" of the network isolated (the cable modem and a fiber media converter, on that one UPS, on its own circuit) by a few feet of glass, from the "inside" of the network (another media converter, wifi router, distribution switch, NAS, etc, on another UPS on a different circuit). There's now no electrical path between the cable HFC network and my inner sanctum, and I haven't blown up any more hardware yet!
Looking at one of these for an external garage where the existing conduit from the house has the electrical supply in it already; don’t want to dig a new trench or work out how to shield cat5/6
And an updated one:
I'm not sure which version these slides correspond to.
The bandwidth and capabilities of fiber and ROADM still blow my mind long after leaving that industry.
