Submarine cables at risk from sea water, boffins warn. Wait, what?

Kernel

"Fancy fibre network with redundant links between two nodes. Unfortunately they were laid in the same ducting, so links not redundant when someone else trenches the street without checking what's in the ground..."

In the past I've worked with a transport system which had full protection at the optical layer - on two different wavelengths of the same DWDM system ie., not even different fibres in the same cable sheath which, if carefully chosen to be on opposite sides of the central strength member, can give a small measure of protection, but on the same fibre pair.

Re: Well you sound smart.

" I'm not aware of any feeds into my dc that are over 100. Still too finicky, and the termination equipment is outrageously expensive at 100."

Most of the stuff I see going in now is 200Gb/s wavelengths and has been for a couple of years - 100G is actually getting pulled out and replaced by 200G by one of my customers - transponders occupy the same or less number of slots, power consumption is less and as a bonus you get twice the data rate per wavelength. I guess the difference is that I work with the same types of DWDM kit that goes on the end of submarine cables, not what goes into data centres - although that said, we do sell routers that will take 400G interfaces and we do now have DWDM transponders that can do 400G coming on to the market.

"Depending in what you can put down on the ocean floor as a repeater, every 30 klicks,"

Or maybe amplifiers rather repeaters, which are limited to their original design rate and protocol - the spacing is usually a compromise between the end-of-life capacity requirement from the customer and how to achieve that with the minimum number of amplifiers. Every amplifier requires 50 volts across it, so a long cable can require as much as 25kV to be supplied, which imposes problems of its own when moving this stuff around.

"It's not like the coastal facility is a data center, it's just a switch/repeater to some inland dc."

I've done work in several landing stations - they are more "just" a switch/repeater and have all included a variety of systems for breaking out sub-rate data streams for the various cable customers in addition to the basic cable terminal equipment - ie.the large and complex power feeding equipment, some form of optical routing/DWDM kit to terminate the fibres and the crucial station earth (just in case the sea earth fails for some reason). At least two of them have included one or more major PSTN switches in addition to data switching/routing kit - months to move, years to plan.

Re: Not really a big issue

I'm assuming you're not familiar with what goes into making a landing station - it most certainly is not easy to take a submarine cable off line and move it. (Hooking it with a ship's anchor and dragging across the seabed doesn't count).

Apart from the new infrastructure build required to replace the landing station, replacing/extending the landing section of the cable would be quite a significant task as it is usually comprised of the heaviest and most highly armoured cable in the system. There's also more than a couple of hours worth of setup and certification work needed once the new landing station(s) have been built - more like days or weeks.

Oh, and don't forget that the cable manufacturer will want to do a feasibility study on your new build, as in some cases there may be an impact on cable capacity - normally the first amplifier is placed on the assumption the landing station is not going to move - if you extend the cable too much an additional amplifier may be required, which will change the power feeding needs of the cable and introduce more noise and distortion to the optical signals. This in turn may mean you are restricted to 10G or 40G/wavelength rather than 100G, 200G or 400G, or perhaps you will not be able to use as many wavelengths.

Re: That's good, but...

"Then there's computing. Colossus was years ahead of everyone else, and yet where is the British computer industry today?"

Arguably one of the most important light bulb moments leading to modern computing was down to Lyons and their extensive chain of tea shops.

They realized that computers could not only work on straight maths problems, but could also be used to assist with solving business problems, like how do you bake and distribute fresh cakes and scones nationally, on a daily basis, with minimum wastage and lost orders.

The Leo series of computers they designed and built to work on this and Lyon's other general business processes (payroll, accounting, etc) were quite innovative for their time and it's unfortunate that the initial lead this gave the UK in commercial computing was never followed up with adequate government encouragement.

"...how useful and representative for real life subjects like computing."

Indeed - how much better it would be for IT jobs to eventually go to people who learnt by looking up canned solutions on-line, rather than figuring it out for themselves like some of the students will be doing.

Oh, wait - we already have this - it's called off-shoring.

Also, note the following:

UK drone collision study didn't show airliner window penetration

Kernel

Invalid testing proceedure?

Ity seems to me that it could be argued that the testing procedure used was invalid, at least for windscreens.

According the the report, the objects were launched towards a stationary windscreen, whereas in actual flight the effect is much more a case of the windscreen being launched towards a relatively stationary object. Presumably some minor effort is put into designing modern airliners so that they have a smooth airflow around them, which I would expect to lift something as light as a hobby grade drone well away from the windscreen before it had a chance to impact it. If you've ever traveled in the rain, in an open top sports car at any reasonable speed, then you've seen this principle at work -yes, the drones are heavier that raindrops, but then the air velocity is much higher as well.

This would not prevent engine ingestion of a drone however - the business of a jet engine is to suck in as much air as possible, including anything that might be floating in it.
