InfraCo 1 3 3 Government needs to intervene here and here what InfraCo proposes to do And NOT here, where the private sector is already competitive 2 1 National Long Distance = Telkom Monopoly, unlikely to change for a number of years to come even with the ECA 2 Metro & Access Networks = Increased Competition likely here under the ECA because lots of players will make local investments. NO NEED FOR GOVERNMENT TO INTERVENE, so NO INFRACO here 3 International Marine Cable Connectivity = SAT-3 monopoly, nothing likely to change here soon.

- 80% of cost is in 1 & 3
- 2002 : Alcatel was awarded a $33 million contract by the SAT-3/WASC consortium to upgrade SAT-3/WASC DWDM submarine cable system at 10 Gbit/s . An "express route" will be created between Portugal and South Africa, ensuring a high capacity connection between Europe and Africa. Alcatel will supply all 2008: WASC Memorandum of Understanding to upgrade to 5.1Tb system with Infraco, possible replacement project for SAT-4 TECHNICAL SPECIFICATIONS (SAT-3/WASC & SAFE SPECS to be laid side by side) SAT-3/WASC Supply contract in force since March 2000 Supplier: Alcatel Submarine Networks (France) System length: 14 350km System type: 4 fibre, OA, WDM System capacity: 120Gb/s ultimately 5.8 m simultaneous telephone calls Landings in Europe, West - and Southern Africa System design life of 25 years SAFE Supply contract in force since December 1999 Supplier: Tycom Submarine Cable Systems (USA) System length: 13 500km System type: 4 fibre, OA, WDM System capacity: 130Gb/s ultimately 6.3 million simultaneous telephone calls Landings in India, Malaysia, Mauritius, Reunion and South Africa System design life of 25 years
- SEACOM PROJECT UPDATE - 14 Aug 2008 Construction on-schedule with major ground and sea-based activities proceeding over the next eight months 14 August 2008 – The construction of SEACOM’s 15,000 km fibre optic undersea cable, linking southern and east Africa, Europe and south Asia, is on schedule and set to go live as planned in June 2009 . Some 10,000 km of cable has been manufactured to date at locations in the USA and Japan and Tyco Telecommunications (US) Inc., the project contractors, will begin shipping terrestrial equipment this month with the cable expected to be loaded on the first ship in September 2008. Laying of shore end cables for each landing stations will also proceed from September. This process will comprise the cable portions at shallow depths ranging from 15 to 50m where large vessels are not able to operate. From October 2008, the first of three Reliance Class vessels will start laying the actual cable. The final splicing, which involves connecting all cable sections together, will happen in April 2009, allowing enough time for testing of the system before the commercial launch in June 2009. The final steps of the Environmental Social Impact Assessment (ESIA) process are well advanced and all small archeological, marine and ecological studies, which required scuba diving analysis, have been completed, as well as social consultations with the affected parties. The cable, including repeaters necessary to amplify the signal, will be stored in large tanks onboard the ships. The branching units necessary to divert the cable to the planned landing stations will be connected into the cable path on the ship just prior to deployment into the sea. The cable will then be buried under the ocean bed with the help of a plow along the best possible route demarcated through the marine survey. The connectivity from Egypt to Marseille, France, will be provided through Telecom Egypt’s TE-North fibre pairs that SEACOM has purchased on the system. TE-North is a new cable currently being laid across the Mediterranean Sea. Brian Herlihy, SEACOM President, said: “ We are very happy with the progress made over the past five months. Our manufacturing and deployment schedule is on target and we are confident that we will meet our delivery promises in what is today an incredibly tight market underpinned by sky-rocketing demand for new cables resulting in worldwide delivery delays. “The recently announced executive appointments combined with the project management capabilities already existent within SEACOM position us as a fully fledged telecoms player. We are able to meet the African market’s urgent requirements for cheap and readily available bandwidth within less than a year. ” The cable will go into service long before the 2010 FIFA World Cup kicks-off in South Africa and SEACOM has already been working with key broadcasters to meet their broadband requirements. The team is also trying to expedite the construction in an attempt to assist with the broadcasting requirements of the FIFA Confederations Cup scheduled for June 2009. SEACOM, which is privately funded and over three quarter African owned, will assist communication carriers in south and east Africa through the sale of wholesale international capacity to global networks via India and Europe. The undersea fibre optic cable system will provide African retail carriers with equal and open access to inexpensive bandwidth, removing the international infrastructure bottleneck and supporting east and southern African economic growth. SEACOM will be the first cable to provide broadband to countries in east Africa which, at the moment, rely entirely on expensive satellite connections.
