Nokia snatches clump of 16nm FinFETs, crafts 576 Tbps monster router

"BT are apparently using these already."

Exactly these (7950XRS XC with FP4 cards) , or the earlier model 7950XRS with FP3?

The 7950XRS is in use in many parts of the world, but the XC version is, as I understand it from the article, a newer model that has just been released.

Re: It's about wavelength as opposed to transceivers.

"That sounds interesting. Are you meaning there are rental agreements for running light through fibre?"

Yes - any modern DWDM system should have the ability to accept what are known as 'alien' wavelengths.

These are 'coloured' optical signals supplied from another carrier and then, after level adjustment, are combined in the optical filters with wavelengths generated by the host system and sent to line. The only processing done to these alien wavelengths by the host system is analogue adjustments, eg., attenuation, amplification, filtering. The host system has no access to the data carried on the alien wavelengths as they are never demodulated into an electrical signal within the host.

This feature is useful if you need to get several wavelengths between data centres in different cities, but don't want to go to the trouble of laying and maintaining your own cross-country fibre network and duplicate what some other carrier has already built.

So, in your data centres you install a base level DWDM box with one or more transponders and no amplifiers. The coloured output from these travels on dark fibre to a national carrier's site, where they are loaded onto a cross-country DWDM system as alien wavelengths - there obviously is a point at which you might decide it's better economics to build your own full DWDM system and lease dark fibre cross-country, but adding optical filters, amplifiers and intermediate amplifier sites adds considerably to the cost.

Re: It's about wavelength as opposed to transceivers.

"40gb/s is accomplished with 4 bonded (think port channel kinda) 10gbs links. That means we need we need 4 wavelengths to accomplish 40gb/s or 10 for 100gb/s. Using WDM equipment, a 40gb/s trasceiver can deliver 10,20,30 or 40gb/s depending on which wavelengths are optically multiplexed."

I work with DWDM systems that do either 100 or 200 Gb/s on a single wavelength (same card, it's just a tick box to switch between them) and I believe there are now 400Gb/s systems starting to come into use - the only reason to use multiple wavelengths is to have multiple independent 100/200 Gb/s channels over the same fibre pair.

Quite possibly it looked much the same - it's the gas filled swim bladder that expands significantly if the fish can't release gas fast enough, not the liquid/solid part of the body

As stated in the article, it's very likely that the cable will be broken is several place due to the tension put on it as the truck was dragged out - the only way to find the breaks is to use an OTDR (Optical Time Domain Reflectometry) to locate the nearest break to the cable end, fix that, test, locate the next break, fix that, rinse and repeat as necessary.

These breaks can be hundreds of metres away from where the truck was bogged.

Radio hackers set off Dallas emergency sirens at midnight as a prank

Kernel

Re: Perhaps they also changed the password

Depending on the age of the system (and they're obviously not overly keen on spending money to keep the technology up to date) it is possibly something as simple as a combination or sequence of tones on a specific frequency. The chances are that the frequency used is a matter of public record from the FCC, thus simplifying the problem considerably.

A $50 programmable dual band VHF/UHF Chinese handheld and a RaspberryPi to generate the tones may well be more than adequate for the task of triggering the sirens - it might even be possible to trigger them just by sending the right sequence of DTMF tones from a handheld's keypad.

Just like controlling a repeater, but more fun.......

Kernel

"So 800 people thought the emergency services needed to be told that the sirens had gone off!"

From what I've been able to find with a quick duckduckgo the population of Dallas is in the region of 2.5 million, so 0.032% of them calling in seems to be a very low number of callers.

The kit required to carry out this little prank is probably very portable and will run quite happily off 12 volts, so, provided the perpetrator has half a brain they should be able to get away with this for years - it could even work out that they are never identified or caught and that the only solution will be a more secure activation system.

Catching this person is going to be about as easy as tracking down some random idiot on the CB bands - in fact, it could well be some random CB nutter who's got bored with spouting drunken on air rants.

Interesting enough, yes, I do.

Nokia's 1830PSS product line has a range of optical router cards as an off the shelf item that are able to extract and switch one or more wavelengths to/from a specific path. There's no technical requirement to convert the optical signal to electrical until you hit a router inside some cable customer telco's network.

This means that wavelengths coming in off the cable can be switched to the different cable customers at the landing station without any requirement to be dropped back to electrical .

I work with Nokia DWDM equipment, using what are referred to as 10Gbps, 100Gbps and 200Gbps wavelengths - but that has nothing to do with the wavelength (or 'colour', if you prefer) of the infra-red lasers. The terms come about because they refer to the transmission capacity of the transponder card that converts from B&W to a specific colour.

Changing from 10Gbps to 100Gbps is just a matter of changing out the transponder at each end of the lambda - in fact, with some transponders, changing from 100Gbps to 200Gbps is simply a matter of clicking an option in the transponder setup page and connecting a second 100Gbps B&W input to the second client port, at which time the single coloured output will move from being a 100Gbps wavelength to a 200Gbps wavelength - but still the same actual wavelength and occupying the same bandwidth, just carrying twice as much data.
