Yeah, set my meter off too.
Fiber has a loss every couple of miles that needs a boost. It's possible they use underwater repeater cases which require power.
I think they need electrical power for switching junctions too.
Single mode fiber can go 35 or 36 miles between repeaters.

I couldn't remember the exact numbers. But yea, that's where a transatlantic cable would need power.
bump for later read
Just FYI, FWIW... for a couple of years, the stretch of I-95 between Savannah and the King's Bay sub base has undergone a vast widening and upgrading, and one of the things that stood out was that they were laying large quantities of thick, multicolored underground cable of some sort. I have been told this is fibreoptic cable. To what purpose, I have no idea, but it's in place now.
Always learning something new here. Thanks...I'll be ready for the quiz ;>) maybe.
The fiber optic cables would not carry any voltage (other than occasional static) the repeaters would be powered but would then go through a electrical to optical interface (converter if you will) where once again the signal is purely optical. BS Indeed!
Could have been flex duct. Makes pulling in future stuff easier. Usually blue, orange, or some other color.
The power is carried within the cable. FITL has a hybrid design like this.
the power to the electrical devices is run along with the optic cable?
Just about EVERYTHING in this article is wrong:
1. You can splice into a submarine cable, but it is difficult to do and easy to detect.
2. There IS power in the cable (unless it is a very short-distance cable, and it used to power repeaters. In fact, the place to "splice in" is at these repeaters since there is no need to splice the fiber at all. Instead, you tap in to the repeater's electronics.
3. You would not "park" a submarine to gather intelligence for more than a very short time. You would run your own submarine cable to backhaul the tapped bitstream.
4. I think all of this crap about tapping submarine cables is a cover story. The way you do it in real life is you bribe someone to let you tap in at a landing point or a SONET switch on land. You backhaul on another lambda to a friendlier place.
Ditto. The whole point of fiber is that it isn't carrying any juice, just light.
Those were the colors. Must be new stuff- I'm familiar with conduit, raceways, trays, and armored cable.
The cable is most likely color coded to identify they type, number and arrangement of fibers running through it, if it is indeed cable. It could also be innerduct, which is used to house fiber in larger, existing ductwork or conduit.
As to the purpose, it could be just about anything related to communications - Telephone, cable TV, Internet, etc. If it's a datastream, fiber will carry it. I know that Verizon has been doing a lot of upgrades to their phone lines, extending fiber into neighborhoods and even preparing to carry cable TV, so you might have seen some of that going on.
Word! Human intelligence beats the high tech stuff any day. There is simply too much "noise" (useless data) in everyday communications to really sort through. It didn't take high tech to pull off 9/11 or the Madrid bombings.
