Tech companies are now laying their own undersea cables

Google, Facebook and Microsoft want more control over the internet’s basic infrastructure

ON SEPTEMBER 21st Microsoft and Facebook announced the completion of a 6,600km (4,100-mile) cable stretching from Virginia Beach, Virginia, to Bilbao, Spain. Dubbed Marea, Spanish for “tide”, the bundle of eight fibre-optic threads, roughly the size of a garden hose, is the highest-capacity connection across the Atlantic Ocean. It is capable of transferring 160 terabits of data every second, the equivalent of more than 5,000 high-resolution movies.

Such ultra-fast fibre networks are needed to keep up with the torrent of data flowing around the world. In 2016 international bandwidth usage reached 3,544 terabits per second, roughly double the figure in 2014. Firms such as Google, Facebook and Microsoft used to lease all of their international bandwidth from carriers such as BT or AT&T. Now they need so much network capacity to synchronise data across their networks of data centres around the world that it makes more sense to lay their own dedicated pipes.

This has led to a boom in new undersea cable systems. The Submarine Telecoms Forum, an industry body, reckons that 100,000km of submarine cable was laid in 2016, up from just 16,000km in 2015. TeleGeography, a market-research firm, predicts that $9.2bn will be spent on such cable projects between 2016 and 2018, five times as much as in the previous three years.

After DataCenter infrastructure (through OCP open-source hardware), Tech companies drill down further the value chain and hit sea bottom with fiber. Software is indeed eating the world yet leads to hardware...

US is closing in on 50-state gigabit goal

US is closing in on 50-state gigabit goal | cross pond high tech | Scoop.it
From www.telecompetitor.com - January 6, 2016 5:42 AM

It’s been almost three years since former FCC Chairman Julius Genachowski set a goal of having at least one gigabit network in every state by 2015. The year is now over and by Telecompetitor’s tally, we didn’t quite make it – but we’re close.

We combed through our archives and other online resources and, by our tally, at least one network operator has announced plans to offer gigabit service in every state. Not all of these networks are actually deployed or supporting service yet. But generally network operators don’t announce specific markets more than a year or two in advance of when they expect to deliver service. If, for example, a network operator simply said it would eventually upgrade its entire footprint beginning in 2016, as Cox Communications did, we didn’t count the company’s entire footprint, only the states it provided more details on.

We also didn’t count a deployment unless plans included residential users. Clearly Genachowski wasn’t talking about gigabit Ethernet service to commercial buildings when he set the gigabit goal.

Gigabit States Even heavily rural states – states such as Wyoming, West Virginia, or Maine – made the list, thanks to a wide range of small locally-focused telcos, utilities, municipal network operators, and others. Even though deployment costs tend to be higher in rural areas, entities with a local focus often manage to find a way to make gigabit happen – and in the telco arena, many companies already had fiber-to-the-home networks, making it relatively easy to upgrade to a gigabit.

Another thing that helped put all 50 states on the gigabit map was that tier one or tier two telco and cable operators that had not previously announced gigabit plans decided to get in on the trend.

On the cable side, Comcast in 2015 launched an FTTH-based 2 gigabit service dubbed Gigabit Pro in several states – albeit in limited parts of each market. Smaller cablecos such as Cable One, Suddenlink, Mediacom  and Troy Cable also made gigabit plans.

And we’re likely to see a lot more from the cable companies in 2016 as they begin to deploy DOCSIS 3.1, which supports gigabit speeds.

Looks like serious catchup is on its way. Wondering how ambitious EU next plan will be...

Verizon Offering 500 Mb/s fiber service for $309/month

From www.bloomberg.com - July 24, 2013 9:16 AM
Verizon Communications Inc., the second-largest U.S. telephone company, is boosting its FiOS Internet speeds to 500 megabits a second, faster than Comcast Corp.’s speediest service and half that of Google Inc.’s.
Philippe J DEWOST's insight:

Most interesting figure to me here is not the speed but the price. I wonder what we will be capable of achieving here in Europe...

AT&T's Project AirGig could be a wireless alternative to fiber

AT&T's Project AirGig could be a wireless alternative to fiber | cross pond high tech | Scoop.it
From www.engadget.com - September 22, 2016 6:27 AM
The project is still in its experimental phase, but AT&T says it's bursting with potential. AirGig's relay stations may sit on top of telephone poles, but it doesn't actually need to tap into the pole's power source -- it doesn't send signals over the lines either, opting instead to regenerate millimeter wave signals from station to station. Because the stations are designed with to use affordable plastic antennas and make use of existing infrastructure, it offers a potential way to bring high-speed connections to new areas without laying down new cable. Not only does that save a ton of money, it also means the new system could be deployed faster.
Philippe J DEWOST's insight:
While europeans break speed records with 1Tb/s on fiber, ATT looks into Wireless Gigabit for rural areas.

Alcatel-Lucent sees 'major breakthrough' in tech for 1,000Tbps speeds

Alcatel-Lucent sees 'major breakthrough' in tech for 1,000Tbps speeds | cross pond high tech | Scoop.it
From www.zdnet.com - November 24, 2015 1:22 PM

Alcatel-Lucent's research arm, Bell Labs, has announced that ongoing testing of its prototype real-time space-division multiplexed optical multiple-input-multiple-output (MIMO-SDM) system could see the company attain speeds of 1 petabit per second in time for the arrival of 5G and the Internet of Things.

 

In what the company called a "major breakthrough", a trial of the 6x6 real-time MIMO transmission technology in New Jersey saw Bell Labs successfully remove for the first time crosstalk from multiple signals on the fibre supporting the six parallel optical signal paths using real-time processing.

 

"This experiment represents a major breakthrough in the development of future optical transport," Marcus Weldon, CTO of Alcatel-Lucent and president of Bell Labs, said.

"We are at the crossroads of a huge change in communications networks, with the advent of 5G wireless and cloud networking under way. Operators and enterprises alike will see their networks challenged by massive increases in traffic. At Bell Labs, we are continuously innovating to shape the future of communications networks to meet those demands."

The successful experiment used six transmitters and six receivers alongside real-time digital signal processing over coupled fibre stretching 60km in Bell Labs' global headquarters.

Philippe J DEWOST's insight:

The race is certainly not over. Nokia might appreciate.

Bell Labs using "noise canceling" to reach fiber optic speed of 400Gbps over nearly 8000 miles

Bell Labs using "noise canceling" to reach fiber optic speed of 400Gbps over nearly 8000 miles | cross pond high tech | Scoop.it
From www.engadget.com - May 28, 2013 2:49 PM

Alcatel-Lucent's Bell Labs has found a way to go that extreme distance by relying on the basic concept behind noise-cancelling headphones. When the researchers send data across two light beams in opposing phases, they can superimpose the signals and neutralize the distortion that would normally occur at long ranges. Such clean output lets Bell Labs ramp up the signal strength and maintain high speeds across whole oceans: its test pushed 400Gbps through 7,954 miles of fiber.

Over 40 Terabits/s across more than 1800 kilometers : Verizon, NEC claim fiber speed records

From www.telecomasia.net - April 12, 2013 1:58 PM

Verizon and NEC said they have successfully sent the highest-capacity transmissions for regional and long-haul distances over field fiber.

 The two companies said tests showed that by expanding from one band to two bands, the C-band and the L-band, the two firms were able to transmit 40.5 terabits per second for a long-haul distance of more than 1,800 kilometers (1,118 miles) and 54.2 Tb/s over a regional distance of more than 630 kilometers (391 miles), using Verizon’s fiber loop outside Dallas. The achievement was accomplished by tightly packing optical channels in the two bands of the optical fiber spectrum, the two firms added.
