Brazil’s Telebrás Plans Major Submarine Cable System
bravata = bravata + 1 mas nem todo o mundo é bobo para acreditar e temos que engolir um artigo publicado em veiculo especializado aonde 50% do texto é ironia.

According to an article on BNamericas, Brazil’s state-owned operator Telebrás is making a big undersea move aimed at dramatically increasing the country’s international bandwidth choices by hooking up four continents.
The first leg they have planned will be from Fortaleza, where many other cables already land, to the obvious initial target, the US. But the second leg will hook up to Europe, while a third will connect to Africa at the Angolan capital of Luanda. And the remainder will make several hops down the east coast of South America to Sao Paolo and on to Uruguay and Argentina. It’s an ambitious project, and the first phase is still a ways off – scheduled for 2014.
Actually, it sounds a bit familiar too, as there was another project recently announced called WASACE that planned to connect the same four continents, albeit via a different configuration . And there is also still the Brazil-Africa cable system said to be planned by a group with Chinese involvement too. The South Atlantic has never been so interesting. If all these cables get built, though, it’s going to take a long time to burn through all that capacity.
All we need now is a South Pacific cable plan. Surely Chile is tired of connecting to everyone the long way around, perhaps a direct link to Tokyo and/or Sydney will turn up soon?

Huge Brazil-Africa Cable Planned
April 18th, 2011 by Rob Powell
According to a report on African site TechCentral, there is a new transatlantic cable in the works. But this time it’s in the South Atlantic, connecting Fortaleza Brazil with Angola and South Africa, destinations that one doesn’t normally think about undersea cable hooking up. The project is being led by eFive Telecoms and will supposedly be built by a joint venture between Alcatel-Lucent and the Chinese government.
Plans for the “South Atlantic Express” cable call for a huge 12.8Tbps maximum capacity, powered by 40Gbps waves over four fiber pairs. Two pairs will land in South Africa, and two will land in Angola The new cable will also provide the shortest route between South Africa and the US, for which the backers have signed a memorandum with GlobeNet. Access to the east coast of Africa and on to southern Asia will be provided via SEACOM.
The planning is at an advanced stage although not yet complete, but the target date for commercial use would be June 2013. Datawave out of the UK is supposed to present its findings on the business case later this month. The governments of Brazil, South Africa, India, Russia, and China have all given their backing. The non-US centric point of view plus that interesting list of backers will surely get some attention in Washington DC – though I’m not sure what will come of it.
Politics aside, the thought of bandwidth demand for 12.8Tbps of data between Brazil and southern Africa is staggering all by itself. Somebody’s thinking ahead – way, way ahead. Unless it’s all a bluff – but they named a whole lot of participating parties, so it seems likely they’re serious.

WASACE Plans Unique, New Transatlantic Cable System
November 22nd, 2011 by Rob Powell
There’s another transtatlantic cable system in the works, according to a rather quiet launch announcement over the weekend. The effort is aimed not at connecting a mere two continents, but four, and will feature 100G technology from the start. I’m still trying to figure out just what they’re aiming for, check out this proposed network map:
So the WASACE cable system would include a North Atlantic leg connecting France and the Eastern Seaboard of the US, a Latin American leg starting in Miami and running down to Fortaleza in Brazil, a South Atlantic leg crossing to West Africa, and then a leg down the West African coast toward South Africa. The main idea I think would be to open some new connectivity options to the southern hemisphere, such as Africa-USA and Africa-South America.
That Brazil-Africa link possibility has shown up twice now, we saw it last year in talk of a giant system financed by China whose status I haven’t heard anything new on.

Telebrás defines 5 segments for submarine cable network
Published: Wednesday, March 7, 2012 16:19 (GMT-0400)
By Pedro Ozores / Business News Americas
A project to link Brazil to the US, Europe, Africa and the South American Atlantic coast via a submarine cable network will have a total of five sections, Brazilian state-controlled telco Telebrás' innovation and technology manager, Paulo Eduardo Kapp, told BNamericas on the sidelines of Capacity Latam, an event for the wholesale telecommunications industry being held in São Paulo.
According to Kapp, the first stretch will connect Brazil's Ceará state capital Fortaleza to the US, with a leg reaching Colombia; a second one will link Fortaleza and Europe; a third cable will leave Fortaleza and reach Africa through Angolan capital Luanda, with a leg connecting the Brazilian archipelago of Fernando de Noronha as well.
Another stretch will connect Fortaleza to the city of Santos, in São Paulo state, with a leg reaching Rio de Janeiro; and a last stretch will join Santos with the Uruguayan city of Maldonado and the Argentine municipality of Las Toninas.
Kapp didn´t provide a schedule for deploying each of stretches, but said the cable linking Fortaleza and the US will be delivered by 2014 - in time for the Fifa World Cup, which Brazil will be hosting.
According to the executive, planning and building a unique submarine cable takes some 18 months. The estimated timetable for the entire project is 5-6 years, he said.
Kapp noted that the government is working with a shortlist of potential partners to finance and operate the project, saying that one of the main specifications is that the company be Brazilian.
"The partner has to be 100% Brazilian, and it must associate with and be part of other companies and consortiums in the sub cable network project," he said.
Local press recently reported that the government was mulling an MOU with Brazilian construction conglomerate Odebrecht to form a JV. The executive would not comment on those reports.
The entire fiber optic submarine cable network project is budgeted at 2bn reais (US$1.13bn).

What Wacs really means for SA consumers
Next month, the gigantic West African Cable System (Wacs) will come online, bringing around 400Gbit/s of submarine fibre capacity to SA at launch. But what does this increase in capacity mean for SA consumers and Internet service providers?
Sean Nourse, executive for connectivity at Internet Solutions, says that although the effects of Wacs may not be felt by consumers in the short term, they most certainly will be felt in the longer term.
“There’s enough capacity coming into SA already; the bottleneck is on national backhaul and the last mile [into homes]. The effect on the consumer all has to do with how much capacity Internet service providers choose to take on Wacs, as they’re already invested elsewhere,” he says.
Nourse says consumers will benefit insofar as service providers having another option for resilience and redundancy should mean better service quality. “But consumers won’t get better speeds for now and, as it’s a net new cost for service providers, you might not see prices fall immediately.”
Until consumers can actually utilise more of the available capacity, Nourse says the cost benefit won’t reach them. “Seacom [along the east coast] made a massive difference in 2009 because there was a need for capacity then, but even though the next cable Eassy was larger the capacity couldn’t be utilised and it didn’t make nearly as much of a difference.”
One of the biggest local investors in Wacs is mobile operator MTN. Karel Pienaar, head of the group’s SA business, says the huge excess of capacity supply will drive the international component of data costs down. “It will eventually benefit consumers in terms of pricing, but also in terms of experience.”
He says both resilience and quality of service are destined to improve and price reductions will be felt first at the corporate level. “We do a lot of provisioning of international corporate bandwidth and wholesale to other operators and they are going to see benefits.”
Pienaar says it will take a couple of months for the effects to be felt and that corporate clients can expect to see pricing changes from around July. He says MTN is already noticing some price reductions in large deals that are still being negotiated.
He says the real bottleneck is in allowing consumers to make use of the added capacity. MTN, he says, is desperate for access to more spectrum that would allow it to roll out commercial networks using next-generation broadband technology.
“Until spectrum scarcity is removed, price changes will be limited,” he says. He adds data demand is growing and MTN has seen a 20%-30% increase in data traffic this quarter. “From one petabyte at the end of last year, we’re now up to 1,3PB in this quarter.”
Lex van Wyk, MD of data centre company Teraco, shares the view that the benefits of Wacs won’t be felt by consumers immediately. Teraco will offer direct access to Wacs bandwidth from its data centre facilities.
Van Wyk agrees that the real bottleneck is in last-mile infrastructure rather than in international bandwidth.
He also expects local content storage and distribution to grow. “Video streaming can now be cached in SA. The last mile is going to be a problem for a while to come, but lots of people are trenching fibre and the spectrum licensing process is making progress, but until that’s done, accessing the capacity is going to be difficult.” — Craig Wilson, TechCentral

The Caine's arcade video initially had most of its viewers from Los Angeles where it was local news. Today, 80% of the viewers are from cities other than LA. And a good 50% of them are from outside the US. Can anyone say for sure where the bulk of viewers of this video will come from next month? Brazil, India, Russia, China, Europe? Nobody knows.
Multiply this problem with a billion video camera-enabled smart phones in 5 years. Even a PhD in Chaos Theory will not be sufficient to figure out the dynamic traffic flows that will be generated across the oceans.
And yet, the carriers are still building point-to-point submarine cables and buying traffic on each one of them for periods ranging from 15 to 25 years. Imagine a private cable being built that takes on the entire risk of selling out traffic on a point-to-point cable and investors putting up hundreds of millions of dollars in debt and equity based on a market research study that shows a forecast of demand and supply on that given route!
Who are we kidding here? The days of "Build it and they will come" are long gone. Remember, if the market researchers were so smart that they could predict traffic flows for the next 15 years, they would not be selling consulting services. They would be out there building cables. The fact is they are making up numbers and the poor investors are getting suckered by the investment banks and the market research consultants. Anybody can create forecasts on a spreadsheet but remember, garbage in is garbage out. Billions of dollars are going to be lost as the private cables go bankrupt one after another. And the sad thing is there is not going to be enough cables where they are required......when the next Caine's arcade will be found somewhere on this planet.
A good example of the kind of foolishness I am talking about is the newly announced BRICS Cable. It has all the trappings of a system that is sure to fail. Started by government heads, it is a political statement with a bunch of consultants. Why would any of these consultants tell the investors that it is technically feasible to build the system but there will be very few customers on the cable because the latencies are too high and there are not enough landing points? Also, 70% of India's traffic originates in Mumbai so the Chennai landing is a mistake. And at a cost of almost a billion dollars for a 2 fiber pair system, the bandwidth is going to be very expensive, not to mention the O&M. Mark my words, this cable will never see the light of the day.
In fact, I would argue that the entire submarine cable infrastructure worldwide is obsolete, may be not from a technical perspective, but surely from a business perspective. The industry is still building the same way it has been building in the 1990s not taking in to account the leaps and bounds at which the Internet applications--especially mobile and video--are changing the requirements of the carriers.
The BRICS Cable is a 34 000 km, 2 fibre pair, 12.8 Tbit/s capacity, fibre optic cable system linking Russia, China, India, South Africa, Brazil – the BRICS economies – and the United States. It will interconnect, amongst others, with the WACS cable on the West coast of Africa, and the EASSY and SEACOM cables on the East coast of the continent. This will give the BRICS countries immediate access to 21 African countries and give those African countries access to the BRICS economies. The projected ready for service date is mid to second half of 2014.

18-04-2012, 11:47 #5In light of the tremendous untapped potential capacity on many existing submarine cables,
it may seem surprising that new cable construction continues around the world. “Capacity
constraints are not driving most new cable projects,” said TeleGeography analyst Tim Stronge.
“Operators are deploying new systems for a variety of reasons, including physical route diversity,
latency reduction, strategic advantage, and the lure of relatively high price margins on some routes.”
Additional submarine cables have been proposed for construction beyond 2013, including several
trans-Arctic systems and four cables between South America and Africa. “While a few of these
systems may be built, it’s likely that many others will fall by the wayside, joining the long list of projects
that never launched, due to a lack of funding or carrier support,” said Stronge.
