back to article Catch of the day... for Google, anyway: Transatlantic Cornwall cable hauled ashore

Google's newest transatlantic subsea cable has finally been hauled ashore in Cornwall, more than a year after the megacorp revealed plans to connect the UK and US. The arrival of the Grace Hopper cable – named after the computer science pioneer – brings the 16-fibre pair (32 fibres) Google-funded cable to Bude on the …

      Harpoon gun humour notwithstanding, you may recall that back in the Summer there was a bit of chinwag going on just down the coast at Carbis Bay. Perhaps final surveys etc were held up in case they detected Biden's nuclear powered escape submarine lurking around?

      Re: cable effort

      Back in 1983 I was building a new garage/workshop in the garden of our newly acquired three bed 1930s semi. As I knew I would need power, etc. for the lathe and other machine tools, I laid a trunking made out of old scaffold poles, loosely connected together end to end with aluminium tubing sleeves, and containing a rope pull through. After concreting the base and building the garage, I used the rope to pull through a steel wire armoured cable, a phone line, and a 15mm water pipe. The cable carried power for the sockets via an RCCB and lighting via a separate fuse, the water pipe supplied an outside tap in the garden, and the phone line carried an extension phone. Pulling it all through was a bit fraught, I borrowed one of those 'Chinese Finger Trap' cable pullers from work and connected the rope, and my next door neighbour did the pulling whilst I wrangled the nest of pipes, etc. in the cupboard under the stairs to ensure they entered the conduit in an orderly fashion. As far as I know, they are still functional, at least, they were when I moved out in 2017.

        Re: cable effort

        The house I grew up in was also a 1930s semi, with the floorboards between the junction box under the stairs to the back door running perpendicular.

        My dad wanted to run power out to the garage and was trying to work out how to do it, when our cat stated nosing around the hole.

        After a lightbulb moment, he tied a string to the cat's collar, took up a single extra floorboard by the back door and my mum opened a tin of tuna at the other.

        Cue the cat making a quick trip under the floor, after which the cable was connected to the string and pulled through.

        Cat enjoyed the tuna.

        Re: cable effort

        My last house was built in the 1950's and had a conduit from the loft to the lounge right next to the TV. It was for a radio ariel in the loft. The diameter was just too small for two standard sized satellite cables so I found some slightly smaller diameter cables and F type connectors. I pulled the two satellite cables, a CAT 5 and a telephone lead down all in one go. My son was feeding it in in the loft and I pulled at the bottom. Very effective until the house was knocked down three years ago.

        In my current house the satellite cables are fed into the loft and then along with network cables they go down through the airing cupboard which abuts a wall above the integral garage, so cables go into the garage and then back into the lounge. As we did a lot of work before moving in (new ceilings, floor boards up for pipe work etc) I was able to run network cables to every room. I've not yet had time to run the power and network cables to the brick sheds.

    Man, that's disappointing. When I think of undersea cables, I still envisage an armoured cable that's several inches in diameter. Not that piddly little thing they've hauled ashore.

    1. Anonymous Coward

      I was thinking the same. I've been involved with a few undersea cables and all were a lot thicker once the armouring was on. They were for the North Sea so had to withstand trawls (and even burying or rock dumping meant they needed a fair amount of protection) - I don't suppose the risks are the same under the Atlantic but, even so, that looks quite lightweight. My first thought was that it was just the dragline in the photos. The actual signal cores would be quite small and I guess the cable technology has moved on. Besides, the thinner you can make it, the more you can spool, so less expensive to install. It comes down to balancing risk and cost.

      Not really there will be no benefit for Cornwall's internet.

      My mum lived in Sennen and those cables probable run right past her front door just like FA:1.

      When they laid FA:1 around 2201 they dug up the A30 as far as her road. Did a right and dug up her road for the last 1/2 mile to the bay. At that time she could not get a decent internet service not even basic as she was too far from the exchange.

      After the work was finished could she decent internet? No still too bloody far from the exchange.

      With the transatlantic cable running within 7 meters of her front door, she could not get speeds much better than dial-up.

      Re: Beach cable baby

      Very different to my recent beach experience. I was at Caister on the Norfolk coast and got to watch a Londoner drive his shiny 4x4 down the private road used to get the lifeboat into the sea to the beach, get a few feet into the sand and then get stuck. Que much thrashing of front tyres (Someone had to point out you needed to actually engage 4WD), followed by much thrashing of all 4 types as he dug himself in even deeper. When someone from the lifeboat org pointed out he shouldn't have been there anyway (Private road, illegal to drive on the beach, blocking lifeboat access), he got all arsey - think petulant but sweary child.

      Fortunately, several people started booing him, telling him to STFU and calling him irresponsible* for having the 4WD and not knowing how to use it.

      We were all praying for a lifeboat callout, as (hopefully) the lifeboat and it's very large tracked Caterpillar launching vehicle would have driven over his 4WD and his tiny dick to get to the sea.

    Another cable ship of a same name sank last year--- our brilliant community/moderators caught my confusion. Thank you.

    Anyway I found an excellent tour of a modern cable ship.

    https://perspectives.mvdirona.com/2017/01/cs-responder-trans-oceanic-cable-layer/

    Repeaters need power. 100 separate feeds would be awkward. They are wired in series like old holiday lights, but with as much redundancy as the topology allows.

    1. AdamT

      Yup - I worked on TAT-9 back in the '90s.

      There are a couple of bits of copper in the middle of the cable (with the fibres inside) - one is just wrapped round as a C and the other is wrapped and then welded (brazed?) into an O. The high-tensile steel cables which wrap that don't contribute that much to the conductivity.

      The regenerators (one per fibre) were powered from the drop across a zener diode so each repeater dropped about 60 - 80V.

      The current was 1.6A and this was achieved by applying about +9kV at one end of the cable (with respect to the big earth rod) and about -9kV to the other end (with respect to its big earth rod).

      Obviously most of the power is lost in the cable.

      The cable forms a crude coaxial cable (with respect to either its armouring or to the sea water as ground) which means you get some "interesting" effects if the cable either breaks or shorts. e.g. 100s of amps of current spike so the zeners were rated to about 500A and the expectation was that the repeaters would survive, a cable ship could repair the break and the cable would be back online.

      Re: It's the first undersea cable...

      I have been told...(by someone who was there)...that in some cables, the repeaters also contain hydrophones, allowing Certain Organizations to listen to passing marine objects, natural and man-made.

        Until we get quantum...

        If that's not true, somebody's security services are asleep on the job.

        In the past, submarines have turned up and spliced in taps. I'm not sure how possible that is now (or how useful, given encryption is widespread) but, aside from general monitoring, a hydrophone would provide awareness that the cable may have been tampered with.

    How long is it?

    Just wondering, if this goes along the bottom, and the average depth of the good old Atlantic is about 3.5km, how long does that make this cable overall? Is it one long piece that the boat has to carry, or is it constructed in sections that are delivered as it goes along its route?

    Thanks.

    1. AdamT

      Re: How long is it?

      Well the cable is broken up into sections of around 50 to 100km length because you need a repeater to boost the signal. So the cable only has to be made in lengths up to that spacing and then the repeaters will be connected in at the appropriate intervals. They do try and do all this on dry land and I think in all but the longest cables the whole lot can be loaded into _huge_ cylindrical tanks which are then loaded on to the ship. There is a lot of very clever handling equipment to deploy the cable from the tank and then, every 100km, the repeater (which will be in a rack outside the tank) without twisting or kinking the cable.

      A transatlantic cable will be several thousand kilometres and I think that can usually be done in one or maybe two goes. The cable length is slightly longer than the actual path as it is laid in a slight S pattern so that there is some slack if it ever needs to be hauled up for repair.

      Ships can do cable jointing and repeater attachment/replacement while at sea, but it is to be avoided if possible! If you thought domestic cable stripping was annoying then here you have to start with an angle grinder and then work your way down the set of tools until you get to the delicate, needs to be kept very clean, fibre splicer. Then work back up sealing everything in and bonding the steel core cables (which carry the tension) and any armouring layers into the "joint" or the repeater end connector. A strange mix of hi-tech and maritime-chunky ...
