We've had subs that do this since the 60's. I'm trying to remember the name of the sub but we had one starting in the 1960's which had doors that open on the bottom so divers could go out and hook up the stuff. We tapped just about all of the Soviet's undersea lines.

errm, how exactly can divers exit a sub with thousands of pounds of pressure? more than likely they used a robotic arm of some sort.

It is consistent. Important presidents get important ships, unimportant presidents get unimportant ships

normally presidents get aircraft carriers.

but this is one of our most advanced submarines. Sure it's small, but it's the pride of the submarine fleet.

holy cow! I never knew Carter was a nuke officer. Same profession as me, except he was an officer and I was enlisted.

My respect for Carter has just went up.

On one of the boats he was the CO.

You cannot tap fiber optic cables unless you cut them and splice something in the middle. IIRC it is extremely hard to do. Besides, you cut a cable and you don't think the other side would notice?

I bet it can be done. After all they're doing it so there must be a way.

in the slot machine business we have what we call amplifiers that can amplify fiber optic signals over long distances. You plug both ends into the amplifier etc. So you don't have to think of fiber optic wires as one continuous strand of glass that can't be broken. They can be broken, it's just you have to make sure the signal continues on it's original course afterwords.

Basically what you'd have to do is cut the wires plug both ends into the machine. And of course this machine would have to be capable of reading the signal, and then broadcasting the same signal.

It seems like a difficult operation to do underwater though.

NO since you are not intelligent I will hint you that the reason wrong way is his wife is because it could be long lay. BUT NO... you wouldn't get it, go on stuff more hamburgers into your fat brains.

Actually, you can have amplifiers that work with an unbroken beam - over a stretch of the cable, you essentially turn it into a laser, and it amplifies the light that passes through that stretch.

I think the "you can't tap the line because you have to break it" crowd is thinking too 1980s.

Technology has progressed since then. Why break the line when you can bypass it and put a splitter on it?

that's probably it.

I don't know enough about the technlogy. But what happens in our machines is the fiber optic comes in and plugs into a comm board. This signal is sent along to the other machines. But somewhere in that comm board lies the ability to modify and manipulate the signal (or the machine wouldn't be able to transmit the information it needs to). And of course when it plugs into the CVT- that machine reads the signal. And it also sends out a signal.

Like I said, I don't know all the ins and outs. I just know how to tell if a comm board is bad, or how to tell if the fiber optic is bad. I just replace one or the other to get the machines up and running.

Yay, the US government can now spy on us even more.

You can't put a splitter on it without cutting the cable.

[Kuciwalker]

And then putting it back together again, so that they can't tell that it was cut. You're point?

[VetLegion]

What Krill said. Cutting the cable and adding electronics will add lag to the signal. This can be detected easily.

Krill's da man in this thread

[Kuciwalker]

How will they detect this lag, except by comparing it to signals... that go through the fiber-optic cable?

And a splitter wouldn't add ANY lag, just decrease signal strength a bit.
