The EASSY has landed!
Landing partner Telkom’s ring around Africa

The East African Submarine Cable System (EASSy) – one of the nine undersea telecommunications cables that will connect various parts of Sub-Saharan Africa to the rest of the world by 2011 – will land at Mtunzini, on the northern KwaZulu-Natal coastline, tomorrow.

Telkom is the South African landing partner for EASSy. In all, there are nine EASSy landing stations in Sudan, Djibouti, Somalia, Kenya, Tanzania, Comoros, Madagascar, Mozambique and South Africa, with shore-end landings already having occurred in Mozambique and Sudan.

"EASSy is one of the elements of Telkom’s cable investment strategy and is a key step towards the process of establishing a Telkom fibre ring capability around Africa," said Alphonzo Samuels, Telkom’s Managing Executive for Wholesale Services.

He added: "EASSy further increases the robustness of Telkom’s international bandwidth offerings and portfolio. Together with other undersea cables and/or land based fibre routes, EASSy creates redundant fibre access prospects into East Africa."

EASSy is a 10 000 km undersea cable system currently being constructed along the east African coastline. Its 1.4 Tbps system design capacity, coupled with its two fibre-pair configuration, equips EASSy with the highest capacity of all undersea cable systems along the east coast of Africa.

Interconnection with various other undersea international cable systems will enable traffic on EASSy to seamlessly connect to Europe, North and South America, the Middle East and Asia, thereby enhancing the east coast of Africa’s connectivity into the global telecommunications network.

"EASSy is routed from South Africa to Sudan, linking the coastal countries of East Africa. An extensive backhaul system linking landlocked countries to the coastal countries has been developed and is at various stages of completion," stated Samuels, adding that EASSy is scheduled to be ready for commercial service from August this year.

Samuels explained that submarine cables held many benefits such as superior transmission quality, considerably lesser delays compared to satellite, high transmission capacity, access to the global optical fibre network, lower unit costs (compared to satellite), no electromagnetic interference and higher resistance against adverse weather conditions.

"However, activities such as fishing and anchoring, ocean drilling, fish bites and earthquakes constituted some of the commonly known submarine cable hazards," cautioned Samuels.

Various initiatives were nevertheless undertaken to protect submarine cables. These included conducting ocean bed surveys to select the safest undersea routes; burying cable in sand where possible, especially at the shallow end; avoiding heavy shipping lanes when approaching landing points; selecting safe beaches, bearing in mind that later beach erosion could expose cables; designing the shortest land cable route for maximum security; and, manufacturing cables to exceed the 25 year design life of the cable system.

"Redundancy, protection and – where necessary – restoration are also key considerations," said Samuels.

He explained: "Redundancy means that we have duplicated equipment at the cable stations, duplicated power converters, generators, etc. Therefore, if a single piece of equipment should fail, we have another piece of equipment standing by to take its place."

Protection ensures that a fully duplicated amount of capacity is available to re-route traffic on the same cable in the event of an internal failure impacting only one path or fibre. Protection therefore implies that for everything that is duplicated, automated switching takes place.

Samuels added that restoration required traffic to be routed onto other cable systems via completely different traffic paths and even different routes. "This usually happens when a complete failure of a cable system occurs, usually via an external influence such as a ship’s anchor breaking a cable, to the extent that ‘in-system'protection on the same system is not possible."

He also explained that customers have a choice between the regular international private lease circuits that includes restoration for their bandwidth or a product that excludes restoration, which would be termed non-restorable bandwidth or traffic.

"It must be emphasised, though, that in the event of submarine cable service interruptions, every attempt is always made to expedite customer services," emphasised Samuels.

Although EASSy will not be commercially active by the time this year’s 2010 FIFA World Cup™ kicks off in June, Samuels stated that "Telkom’s undersea capacity has been significantly upgraded". "For example, by end-October last year, SAT-3 and SAFE were upgraded to at least three times their former capacity."

He added that SAT3 provided the shortest route to Europe while SAFE was the shortest link to Asia. From an undersea capacity perspective, therefore, it’s all systems go for the World Cup," emphasised Samuels.

As its investment in EASSy highlighted, Samuels said that Telkom had a robust strategy with regard to undersea cable investments. The Company’s cable investments included COLUMBUS3, SEA-ME-WE3 (South East Asia-Middle East-Western Europe), SAT3/WASC/SAFE (South Atlantic Telecommunications / West Africa Submarine Cable /South Africa Far East), EASSy, EIG (Europe India Gateway) and WACS (West Africa Cable System).

"Our investments are geared by the participation of other operators and we firmly believe that investment sharing translates to better unit costs and improved customer prices," he added.

"Ultimately, we believe that EASSy will also go a long way towards increasing Africa’s bandwidth capacity, affordability and create increased diversity and fibre redundancy between SA and Europe as well as within East Africa" concluded Samuels.
