Cable Compendium: a guide to the week’s submarine and terrestrial developments

18 Aug 2017

Globe Telecom has commercially launched services over the newly deployed trans-Pacific Southeast Asia-United States (SEA-US) submarine cable system linking the Philippines and Indonesia to the west coast of the US via Guam and Hawaii. The 15,000km submarine cable, which was built by equipment vendor NEC, is owned by a consortium comprising Globe Telecom, Hawaiian Telcom, Telekomunikasi Indonesia International (Telin), RAM Telecom International (RTI), Teleguam Holdings (GTA), GTI Corporation (a member of the Globe Telecom group of companies) and Telkom USA. The 100G system – which bypasses congested, earthquake-prone areas – will deliver 20Tbps capacity, and will have a minimum of 25 years of commercial life.

Southern Cross Cables and Hong Kong-based EGS have successfully mapped 15,000km of seabed to find the optimal route for laying the USD350 million NEXT submarine cable aiming to connect Clovelly (Australia) with Los Angeles (US). The NEXT project will interconnect with existing Southern Cross systems, as well as 15 cable station and data centre locations currently accessible by Southern Cross Cables across Australia, New Zealand, Fiji, Hawaii and the US. The NEXT cable is expected to provide an additional 60Tbps of capacity for customers when completed in 2019, adding to the existing 20Tbps of capacity of the current Southern Cross systems. As previously reported by TeleGeography’s Cable Compendium, EGS commenced the marine survey for the submarine link in March 2017.

Wholesale carrier Angola Cables has commenced construction works on the South Atlantic Cable System (SACS) in Sangano, located in the Quissama municipality. SACS is a 40Tbps cable – 6,165km in length – with four fibre pairs that will connect Angola to Brazil, linking Africa and the Americas; the cable is expected to be ready for service (RFS) by mid-2018.

Denis O’Brien, chairman and founder of Digicel Group, reportedly holds the largest stake in Saint Lucia-based Deep Blue Cable, which is aiming to link a number of Caribbean islands to the Americas via a submarine cable, The Gleaner writes. Deep Blue CEO Stephen Scott said: ‘Deep Blue Cable and Digicel Group have a common shareholder, but Deep Blue Cable has its own management team and is separate and distinct from Digicel Group.’ The Pan-Caribbean system will span 12,000km with initial landing points in the Cayman Islands, Curacao, Dominican Republic, Haiti, Jamaica, Puerto Rico, Trinidad & Tobago, Turks & Caicos Islands and the US, in addition to three other markets. The submarine cable network will have an initial capacity of 6Tbps per fibre pair. The new system will utilise TE SubCom’s optical add/drop multiplexer (OADM) branching unit technology, and will be RFS in the first quarter of 2020.

Telefonica International Wholesale Services, the international infrastructure arm of Spain’s Telefonica Group, has announced that it has upgraded the 25,000km South America-1 (SAm-1) cable connecting Argentina with the US and Central America, Efe news agency writes. Telefonica said the enhanced network will ensure fewer disruptions to service. The South American-1 cable offers the company four alternative terrestrial routes to maintain connectivity, with two submarine routes traversing the Americas.

Global Marine Group has been contracted to undertake an emergency repair of Segment 1 of the North Sea Com 1 (NSC) fibre-optic cable in the North Sea. The duration of the cable repair will approximately take four days, depending upon weather or other operational conditions.
