    By Submarine Cable NewsFeed

    Alcatel-Lucent and Fujitsu have announced

    that they will be upgrading the capacity of the SEA-ME-WE-4 submarine cable system that connects numerous countries from Singapore to France. With completion

    scheduled in 2009, this multi-million dollar second upgrade project will further double the existing trunk capacity of the system, going beyond the original design

    capacity, enabling SEA-ME-WE-4 to support the increased broadband traffic requirements along the route.

    Owned and operated by 16 carriers, SEA-ME-WE-4 spans

    nearly 20,000 km linking 14 countries from France to Singapore via Italy, Algeria, Tunisia, Egypt, Saudi Arabia, the United Arab Emirates, Pakistan, India, Sri

    Lanka, Bangladesh, Thailand and Malaysia with 16 landing points. Alcatel-Lucent and Fujitsu had supplied the initial SEA-ME-WE-4 network that started commercial

    operation in the fourth quarter of 2005. The network's capacity was subsequently tripled in the third quarter of 2007.

    Alcatel-Lucent had the turnkey

    responsibility of this state-of-the-art network from design to laying for Segments 2, 3, and 4 linking Mumbai to Marseilles, as well as the overall responsibility

    for the synchronous digital hierarchy end-to-end realization. Fujitsu had the turnkey responsibility of this state-of-the-art network from design to laying for

    Segment 1 linking Singapore to Mumbai.

    Under the terms of the contract, Alcatel-Lucent will upgrade the India-France submarine link by deploying, installing

    and commissioning additional dense wavelength division multiplexing equipment (DWDM), based on its 1620 Light Manager. In addition, Alcatel-Lucent will upgrade the

    1626 Light Manager-based terrestrial link connecting Alexandria and Suez, and the existing SDH equipment, the Alcatel-Lucent 1678 Metro Core Connect, for this

    extensive network.

    Fujitsu will upgrade the Singapore-India submarine link by deploying, installing and commissioning additional dense wavelength division

    multiplexing equipment (DWDM), notably its FLASHWAVE S650 for this extensive network.

  • Algeria Suffers Net Blackout

    By Kieren McCarthy

    Algeria experienced an internet blackout Thursday after a submarine cable that carries much of its traffic failed.

    The SMWE4 Annaba to Marseilles suffered a "technical problem," according to Algeria Telecom. Usually with submarine cables that means it has been accidentally cut, either by a trawler, or ship dragging an anchor, or even a shark attack.

    The problem caused a complete failure of the Oran Link network; Algeria Telecom has routed its traffic through Palermo in order to keep data flowing. Algeria Telecom put out a statement saying its technical team is working on locating the problem and that it would make information about it public once confirmed.

    By Submarine Cable NewsFeed

    Batelco has announced that, in view of the

    recent undersea cable damage that caused inconvenience for Internet users from Egypt, across the Middle East to India, and its customers in Bahrain, it will credit

    their customers' Internet accounts with 50% of their monthly rental broadband charge. For example a customer on a BD10 per month package will receive BD5


    "Even though no Batelco customer lost their Internet access throughout this period, we are aware that they experienced slow downloads due to

    congestion. Our engineers started to re-route traffic within minutes of the cable cuts and our investments in network diversity served us well to restore

    significant connectivity on remaining operational cables and satellites," said Batelco Chief Executive Peter Kaliaropoulos.

    The cable cuts lasted just over

    12 days. Within a few days 65% of capacity was restored for Batelco's customers. Batelco's investments in three cable systems, satellite services and engineering

    planning provided ample redundancy and diversity and no customer lost complete internet connectivity throughout the 12 days, the company said in a

    superior and a more diverse infrastructure than any other operator in the Kingdom which serves as a robust and efficient national backbone to access the world-wide

    web," Mr. Kaliaropoulos said.

  • SEA-ME-WE-4 Repaired

    By Submarine Cable NewsFeed

    Although it was not announced widely

    at the time, SEA-ME-WE-4 was brought back into service on February 9, nine days after it and FLAG's FEA cable were cut off Egypt, causing a major outage for

    Internet users in the region and fueling numerous conspiracy theories. All of the major cables involved in the series of outages are now back in service and

    carriers are reporting that they are serving their customers normally.

  • SEACOM network disturbance caused by extended repair work on SEA-ME-WE 4 cable


    SEACOM experienced an interruption in its service on 14 April 2010 which lasted around seven minutes as a result of a fault on the Mediterranean section of the SEA-ME-WE 4 submarine cable system, which SEACOM currently utilizes to connect to London.

    SEA-ME-WE 4, which stretches from South East Asia to Europe via the Indian Sub-Continent and Middle East, was initially scheduled to undergo repairs to fix the affected fibre pair in the Mediterranean Sea on Saturday 17 April 2010 but this was subsequently rescheduled to Saturday 24 April 2010. However, due to ongoing maintenance activity on another cable network servicing Africa and poor weather in the Mediterranean Sea, the actual work only began on Sunday 25 April 2010 resulting in the SEACOM service experiencing interruptions from around mid-day on Sunday.

    The ongoing repair work is affecting several cable systems and has impacted negatively on the overall Internet connectivity in many regions across the Middle East, Africa and Asia, which rely to some extent on the availability of the SEA-ME-WE 4 cable for global connectivity.

    Operators that have opted to work with SEACOM to find alternative channels have been routed to an Internet Access point in India to maintain service. The repair work is managed and controlled by SEA-ME-WE 4 who has indicated that the repair window may be extended to Friday 30 April 2010 for reasons unknown to SEACOM at this point. SEACOM will continue to provide updates as more information becomes available.

  • SLT Significantly Strengthened Its Multiple Global Connectivity Options

    By Sri Lanka Telecom

    Sri Lanka’s leading ICT solutions provider and National Backbone operator, Sri Lanka Telecom (SLT) is aggressively pursuing new markets in the region. Building international connectivity is a key aspect of this strategy. SLT’s global coverage was significantly strengthened via multiple undersea optical fibre cable systems: SEA-ME-WE 3, SEA-ME-WE 4, Bharat-Lanka (between India and Sri Lanka) and Dhiraagu (between Maldives and Sri Lanka). Sri Lanka’s geographical location makes it a natural nexus for communications in the Indian Ocean basin and helps ensure that the country plays a key role in the process of unfolding new technologies across the region.

    Following a recent upgrade to the SEA-ME-WE 4 by SLT, capacity increased by 3 folds that enabled the system to accommodate much higher speeds using 100G technology, the cable with higher capacity became available for commercial use at the end of 2014. Cable commissioned in 2005, the SEA-ME-WE 4 system is an ultra-high-capacity fibre-optic submarine cable linking South-East Asia to Western Europe via the Middle East. Utilising linear fibre network architecture, this 18,000 km cable is equipped with a total of 16 landing stations. The SEA-ME-WE 4 cable network is owned by a consortium of 17 leading telecom carriers from 15 countries. SLT has developed important partnerships through its involvement in this project. Key among them are the relationships forged with near neighbours Bharti Infotel and Tata Communications (India) and Dhiraagu (Maldives).

    Mr. Dileepa Wijesundera, Group CEO of SLT commented that, “SLT investments continued to further strengthen country’s Global Connectivity as a key strategy devised to support the national objective of making Sri Lanka the Digital Hub of the region. Also the company has focused on capacities required for future data demand. SLT has become a member of the 20-member international consortium that owns the SEA-ME-WE 5 international undersea cable system and is currently in the process of implementing yet another future proof project to serve country’s data demand for the next 25 years”.

  • Submarine Cable Maintenance Near Singapore May Lead to Internet Disruption from Sunday


    Internet speed in Bangladesh may slow down for five days as maintenance work is being conducted on the submarine cable near Singapore, says state-run Bangladesh Telecommunications Company Ltd (BTCL).

    The internet speed in Bangladesh may slow from 12:00am Sunday Oct 23 to 2pm Thursday Oct 27, BTCL Director (Public Relations and Publications) Mir Md Morshed told

    BLTC has made several steps to ensure users will have Internet access during that period, said Morshed.

    “We hope our users will not have too much trouble, but Internet speed may be slightly slower,” he said.

    A ‘repeater’ will be replaced during maintenance work scheduled on Sunday, said a senior official at Bangladesh Submarine Cable Company Limited (BSCCL).

    “There may be Internet traffic outage for about three hours after midnight on Sunday,” he said “And there may also be a three-hour outage on the final day of maintenance work.”


  • Submarine Cable Plans To Sell Bandwidth To Italian Firm At Low Price

    By Muhammed Zahidul Islam, The Daily Star

    Questions have been raised over a move by Bangladesh Submarine Cable Company Ltd (BSCCL) to sell off half of its capacity to an Italian company at a very low price.

    BSCCL has sent a proposal to the post and telecommunication division for approval to sell half the capacity of the SEA-ME-WE-4 cable to Telecom Italia Sparkels.

    In February, the BSCCL board decided to sell four million MIU*km (minimum investment unit), which is equivalent to around 90 Gbps, at a price of Tk 16 crore for the rest of the lifetime of the cable. A submarine cable usually lasts 20-25 years, and this cable has been in operation since 2006; so, the Italian company may be looking to use the cable for 11 to 16 more years.

    In addition, Italia Sparkels will pay BSCCL Tk 48 lakh a year to bear maintenance costs, as Bangladesh is still a member of the consortium -- SEA-ME-WE-4.

    At present, BSCCL has a total capacity of 8.9 million MIU*km, which is equivalent to 200 Gbps.

    The BSCCL cable is connected from France to Singapore and it is easy for the company to sell out capacity or connectivity from anywhere on this route.

    However, telecom division officials and analysts are also raising questions over the bandwidth price and capacity.

    The Italian company's price is around 60 times lower than the bandwidth export price to India, officials added.


  • VSNL Restores Internet Services within 24 Hours

    By Submarine Cable NewsFeed

    India's VSNL confirmed that the company

    restored a majority of its IP connectivity into the MENA region within 24 hours of the Egypt cable breakdown on Thursday. In a statement released to the media, the

    company reported the following:

    On January 30, 2008, the SEA-ME-WE 4 and other undersea cables were severed off the coast of Alexandria, Egypt. These cables

    serve as the principal Internet connections between the Middle East and westward on to Europe and North America. They also connect the Indian subcontinent and South

    East Asia. The impact of the cut cables resulted in degraded Internet service to and from the Middle East. VSNL has an Internet backbone that circles the world

    allowing both eastward and westward connectivity from all regions, a major differentiator among carriers. This allows VSNL to leverage its ownership in a vast array

    of diverse undersea and terrestrial cables assets.

    "VSNL is proud of the team effort that united the company's network and operations teams across three

    continents to execute an ambitious recovery plan in 24 hours," said Radwan Mousalli, Managing Director - MENA, VSNL. "Our cable layout and design allowed us to

    survive a double cable failure as well as develop enough capacity eastward across the Pacific for the internet to reach North America and Europe."


    many other carriers in the region lost service completely, VSNL was able to restore majority of their Middle East customers traffic utilizing the SEA-ME-WE 3,SEA-

    ME-WE 4 eastbound and TIC cable following the cut. Unlike other carriers, VSNL's global undersea presence and strength of technical expertise allowed the company

    to continue service through multiple cable systems. Many enterprises chose to buy from cable operators who have capacity on a number of systems because protection

    is nearly guaranteed and if necessary, restoration is achieved quicker.

    In the case of India too services were largely restored within 24 hours of the cable

    cut by diverting traffic through the TIC and SEA-ME-WE 3 cables.
