I stayed at bed and breakfast down near Gig Harbor Washington, home to one of the most massive Naval bases on the US West coast. We got inside, and the hostess were a homemaker and a man retired out of the navy. While she was showing my wife the decorating, he took me downstairs to his man cave / bar for a drink. On the bar was a weird item in a glass presentation case. He asked me to guess what it was and me knowing quite a bit about things immediately identified it as a section of an undersea Communications cable. This man was the former commander of the nuclear submarine USS Flounder, in a secret Mission decades ago,his crew located on the sea floor, and removd a section of Russian undersea military communications cable and added a recording device and this was a section of that cable taken on that mission.

The crossing was well marked and I heard the barge operator got some healthy fines. Someone had to pay for our hard work! :)

Seems like an ideal private industry/government "partnership." If you want a network of hydrophones on the sea bed to track.. aquatic activity.. they naturally need some data communications. And if the cable operator needs amplifiers ("easy") or repeaters (harder/more expensive) those would seem to be an ideal place for such a thing. These days under the Atlantic, you can avoid needing any repeaters -- devices that recover bits and remodulate/retransmit them -- using low dispersion fiber and optical amplifiers. You can deploy an optical amplifier that will increase the signal level of all the wavelengths of light in a fiber used in a DWDM (dense wavelength division multiplexing system.) This is very powerful because it doesn't have to split out each wavelength, detect the signal, retransmit with a laser for each wavelength, and then recombine. The optical amplifier works on all the wavelengths "at once". But this is where you need "low dispersion" fiber. Imagine that you transmit a single pulse of light (on a particular wavelength/color). As those photons propagate down the glass fiber, they don't all take exactly the same path through the glass. So that pulse of light will start to "spread out" as it travels through the fiber. And the problem is that it spreads out too far and smears into the previous and next pulse. Low dispersion fiber is carefully made using magic and physics and fancy manufacturing to keep the photons nudged closer to a single path down the middle of the fiber. The extreme version of this is "single-mode" vs. "multi-mode" fiber. There is an amazing amount of engineering going on with these systems, and over the last decade or two, the systems are constructed to carry data as the first-class, primary customer, rather than synchronous TDM traffic of multiplexed phone calls. The hand-off to customers looks like an ethernet, and cable operators have much more flexible bandwidth allocation tools available that didn't exist in the past with SONET/SDH transport systems.

Some of this is undoubtedly true. We had cables which did NOT have a steel cable wrapping, with very high voltages in them. The copper outer shell did not contain magnetic fields hardly at all, and mostly by eddy effects. Leakages were high. We did one job, where the strength members were all Kevlar or Aramid fiber. In that case it did not matter if anyone tapped it, since it was just going to an undersea oil drilling tooling fixture, and everyone knew what was going on.

This was not a hard tap. No penetration of the cable occurred. The equipment recorded the electrical and magnetic fields given off by the telephone wires through the cable casing. While there were multiple phone lines in the cable - it apparently was a small enough number to be able to separate their electrical signatures and individual conversations and data was recorded. The data was recorded on tape (very large tape reel), with the monitoring probe switched something like every 6 months. So all conversations and data recovered was at least a month old and could be 7 months old by the time the tapes got back to the secure lab that listened to them. Another key was that the Soviet Union thought this cable was secure and there was no encryption of voice or data at the time. Today, everyone assumes that no form of communication is secure and extensive encryption is now routinely used for classified data and conversations.

One of the most interesting aspects of this story, to me, is the lag between the first transatlantic telegraph cable, and the first tele-phone- cable, TAT-1, almost 100 years later!! And half a century after Marconi spanned the Atlantic with radio in 1906. You would think the transistor ultimately enabled it, and of course that had to wait until 1947. But they were new and un-tested. It was all done with tubes.

@kenoliver8913

Bandwidth requirements for telegraph (binary Morse code) and telephone (voice) are RADICALLY different. The capacitance of the cable really affects that - and seawater is a wonderful dielectric (ie a cable under it creates a massive capacitor).

Even mobile phones are only wireless to the nearest cell tower then it's all wired networks. Yet common joe seems to have this belief that all comm systems talk together due to pure magic.

thank you for your work,; high quality stuff, everything you do!

The first undersea telegraph cables were in the 1850s - 1860s and the whole world was connected by about 1900. But all of those cables were just that, a big long wire, and enormous voltages were used to send messages very slowly. Telephone and high speed data needs amplifiers and electronics. That wouldn't happen until 1956 with TAT-1, which had miniature highly reliable vacuum tube amplifiers built into the cable, every hundred miles or so. Up to 36 simultaneous phone calls between Canada/US and the UK.

Kurt Vonnegut has a character in Cats Cradle comment acerbicly about authors who do their own index.

Just last night I was reading Tom Standage’s “The Victorian Internet” which discussed the first attempts at laying undersea cables.

Also check out a 1996 article in Wired magazine about these cables, by Neal Stephenson, the sci-fi author. Sadly, pay-walled.

@@jxh02 That was such a good article that I kept the physical magazine just for it. It's still in my tech library to this day. Just Brilliant!

There is a huge amount of sabotage on opposing efforts. Once somebody went and drove a steel needle into one

Was going to mention this book too, it's a good read. That section on those first attempts was pretty hilarious

Next may be power sea cables. Some projects are on the table. Mainly, the Morocco-UK.

How are repeaters powered? Do they even require external power source?
