安哥拉光缆集团计划投资建设一条从安哥拉到巴西的海底光缆
据法国《论坛报》(La Tribune)4月20日的报道,安哥拉光缆集团Angola Cables计划建设一条从安哥拉到美国、巴西的海底光缆。
这条海底光缆总长度为6165公里,内含4对光纤,每对光纤带宽为100 Gbit/s, 将新增40 Tbps的流量。该光缆将为整个西非地区的国家提供高速宽带互联网传输服务。


安哥拉光缆集团20日发布新闻稿,宣布已完成该项目的可研,该项目被命名为“南大西洋光缆传输系统”(The South Atlantic Cable System ,SACS)。项目建成后,该条海底光缆将联通巴西、美国和整个西非地区。
该项目计划采购日本NEC公司的设备和光缆, 施工工程则委托给美国Ocean Specialists Inc (OSI)承建。

Internet : un nouveau câble sous-marin reliera l'Afrique aux Amériques

Un nouveau câble reliera l'Afrique au l’Amérique latine, renforçant ainsi le branchement du continent au reste du monde. Le nouveau système de câblodistribution sous-marin, qui sera réalisé par Angola Cables, donnera ainsi à toute la région de l'Afrique de l'ouest à une connexion additionnelle de 40 Tbps à travers des câbles de 6.165 km de longueur, avec quatre paires de fibres qui relieront l'Angola au Brésil.
Bonne nouvelle pour la connectivité africaine à Internet. L'opérateur international des infrastructures télécoms, Angola Cables, vient d'annoncer l'achèvement des études pour l'installation du Système de câblodistribution de l'Atlantique Sud (SACS), ainsi que le démarrage du chargement du câble sur le côté angolais du système. La fin de cette étape annonce ainsi le lancement des travaux pour installer ce câble qui, une fois terminé, s'interconnectera avec le système de câblodistribution sous-marin reliant les États-Unis et le Brésil avec l'Afrique de l'Ouest.
Le projet est de taille. Il permettra une connexion de 40 Tbps à travers des câbles de 6.165 km de longueur, avec quatre paires de fibres qui relieront l'Angola au Brésil, reliant ainsi l'Afrique et les Amériques. Chaque paire de fibres sera capable de transmettre 100 longueurs d'ondes avec une bande passante de 100 Gbit/s.)
Les études qui viennent d'être achevées permettent d'identifier la meilleure voie pour l'installation des câbles, évitant ainsi les points dangereux, un facteur crucial pour assurer la longévité du système. Ainsi, la fabrication finale peut être complétée et tous les réglages mineurs de l'itinéraire des câbles peuvent être ajustés en fonction des résultats réels de l'enquête.
Durant ce projet, Angola Cables achètera ses matériaux chez l'opérateur nippon NEC Japan, quant aux travaux, ils seront exécutés et supervisés par la firme américaine, Ocean Specialists, Inc (OSI).
Qui est Angola Cables ?
Angola Cables est l'un des 12 membres du consortium qui gère système de câblodistribution de l'Afrique de l'Ouest, et l'un de ses plus grands actionnaires. Il fournit déjà ses services de transmission de bandes passantes aux opérateurs télécoms de l'Angola et dans onze autre pays de la région. Le système que l'opérateur gère est composé principalement d'un câble de 14.530 km allant de Yzerfontein (en Afrique du Sud) à Londres. Le système est composé de quatre paires de fibres et comprend 14 points d'atterrissage, dont 12 le long de la côte ouest de l'Afrique (y compris le Cap-Vert et les îles Canaries) et deux en Europe (Portugal et l'Angleterre).
A quoi servent les nouveaux câbles ?
Concrètement, si les prix de la connexion à Internet restent particulièrement élevés dans beaucoup de pays africains, c'est principalement dû au manque d'infrastructures télécoms, dont les câbles terrestres et sous-marins constituent l'épine dorsale. Bien entendu, des avancées considérables ont été réalisées. Rien qu'en observant les prix de la connexion dans les pays situés sur littoral, l'on constate que plus l'on s'approche du branchement intercontinental, plus le prix diminue. Par exemple, au Ghana, il est situé à 7 dollars par mois, en Afrique du Sud à 55 dollars par mois, alors qu'au Tchad des tarifs restent très élevés. A 600 dollars par mois, il est tout à fait compréhensible pourquoi il n'y a que 3% de la population tchadienne qui a accès à internet.
安哥拉光缆公司Angola Cables发布的新闻稿
LUANDA, Angola, April 20, 2017 /PRNewswire/ -- Taking a step closer to completing a valuable new route for the global telecommunications sector, Angola Cables today announced the completion of the marine survey for the South Atlantic Cable System (SACS), as well as the start of cable loading on the Angolan side of SACS. Marking an important milestone in the development of the globally relevant project, when completed, SACS will interconnect with the Monet cable system — connecting the United States and Brazil — and WACS, the West Africa Cable System.
SACS is a 40 Tbps cable — 6,165 km in length — with four fibre pairs that will connect Angola to Brazil, linking Africa and the Americas. (Each fibre pair is capable of transmitting 100 wavelengths with a bandwidth of 100Gbit/s.) Angola Cables is one of the 12 members of the consortium that manages WACS (and one of its largest shareholders), a cable system which provides carrier level services to operators in Angola and Sub-Saharan Africa across 11 countries. As a 14,530 km cable running from Yzerfontein (South Africa) to London (UK), WACS has four fibre pairs and includes 14 landing points, 12 along the western coast of Africa (including Cape Verde and Canary Islands) and two in Europe (Portugal and England).
With the marine survey successfully completed, Angola Cables assures that the cable will be deployed in the best route, thus avoiding hazardous points, a crucial factor in ensuring longevity of SACS. Completion of the marine survey means that final manufacturing can be completed and any minor route and/or cable type adjustments can be fine-tuned based on the actual survey findings. With the loading of the Pre-Laid Shore End (PLSE) the construction of SACS is underway. For this aspect of the cable system, Angola Cables commissioned NEC Japan and contracted Ocean Specialists, Inc (OSI) to oversee the construction process, all to assure the highest levels of quality.
"We have worked closely with our partners and suppliers to ensure the highest possible value of the SACS network for our customers," said Antonio Nunes, CEO of Angola Cables. "As part of our global connectivity strategy, SACS will offer the first direct, high-capacity southern transatlantic connection."
SACS to be ready by the middle of 2018
"These key milestones illustrate that the SACS cable is on target for completion as Angola Cables continues to build sales momentum for delivery of services on SACS by the middle of 2018. Increasingly, customers are turning to the southern transatlantic route for diversification and security. SACS, coupled with Monet and the existing WACS cable, provide unparalleled value for which we are seeing very high demand in the marketplace," added Artur Mendes, Chief Commercial Officer for Angola Cables.

First submarine cable to cross the South Atlantic is set to be brought fully online in the second half of 2018 with a bandwidth of 100Gbit/s.
The loading of a cable connecting Angola to Brazil has been initiated on the African shore as related marine surveys conclude.
The South Atlantic Cable System (SACS) will measure 6,165 Km in length and land in Fortaleza on the Brazilian side and at Sangano beach, Luanda, on the Angolan side.
Completion of the marine survey means that final manufacturing can be completed and any minor route and/or cable type adjustments can be fine-tuned based on the actual survey findings.
The cable has been designed with four fibre pairs with each fibre pair capable of transmitting 100 wavelengths with a bandwidth of 100Gbit/s.
The SACS is to interconnect with the Monet cable system — connecting the United States and Brazil — and WACS, the West Africa Cable System.
