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

14 Jun 2019

The US Department of Homeland Security (DHS) has published a petition stating that it has no objection to the Federal Communications Commission (FCC) approving GCI Communication Corporation’s (GCICC’s) application for a licence to land and operate a non-common carrier fibre-optic submarine cable system in the US. The AU-Aleutian system, renamed from TERRA-Aleutian in April 2019, will connect a number of communities in Southwest Alaska and the Aleutian Islands, with eleven new landing points in Akutan, Dutch Harbor, False Pass, King Cove, Cold Bay, Sand Point, Perryville, Chignik Bay, Chignik Lagoon, Chignik Lake and Larsen Bay, while the landing at Kodiak will use a previously constructed landing station. The new cable will have a total length of 1,456km, and will comprise 15 segments: Dutch Harbor to Akutan Branch unit (58.5km, twelve fibre pairs), Akutan-Akutan Branch unit (27.3km, twelve fibre pairs), Akutan Branch unit-False Pass Branch unit (212km, twelve fibre pairs), False Pass-False Pass Branch unit (44.2km, twelve fibre pairs), False Pass Branch unit-King Cove (60.7km, twelve fibre pairs), King Cove-Cold Bay (43.1km, six fibre pairs), King Cove-Sand Point (175.9km, six fibre pairs), Sand Point-Perryville Branch unit (118.4km, nine fibre pairs), Perryville-Perryville Branch unit (45.9km, six fibre pairs), Perryville Branch unit-Chignik Bay (135.5km, nine fibre pairs), Chignik Bay-Larsen Bay Branch unit (326.8km, six fibre pairs), Larsen Bay-Larsen Bay Branch unit (37.2km, twelve fibre pairs), Larsen Bay Branch unit-Kodiak (135.7km, six fibre pairs), Chignik Bay-Chignik Lagoon (16.5km, six fibre pairs), and Chignik Lagoon-Chignik Lake (18km, six fibre pairs). GCICC, which will wholly own and operate the AU-Aleutian system, is aiming to commence commercial operations over the system in Q1 2020.

Internet services in Vietnam have now been fully restored after a fault in the Asia-Pacific Getaway (APG) undersea cable system was fixed last week. The APG submarine cable linking Vietnam to a number of Asian countries suffered a fault 132km away from Danang on 27 May, affecting internet connections in the country. It was the fourth time this year that the 10,400km APG cable, which was installed in January 2017, experienced technical difficulties.

Russia’s Rostelecom and Kazakhstani operator Transtelecom have signed a Memorandum of Understanding (MoU) for the construction of a cross-border crossing linking Ozinki (Russia) and Semiglavy Mar (Kazakhstan). The new network will provide 200Gbps of bandwidth between the two states.

A new metro fibre-optic cable has been inaugurated in South Sudan. Deng Biar Deng, managing director of Vertigo Communication, said the fibre-optic cable will support the government in extending services to post-conflict communities: ‘The metro ring will enable [a number of] institutions to tap into the infrastructure we have laid to enhance the tools of education.’ The move comes less than a month after the government launched its own international voice gateway in the capital Juba.

Ethio Telecom has entered into an agreement with Djibouti Telecom to use the fibre-optic cable deployed along the Ethio-Djibouti Railway for telecommunication services. The 784km railway runs from the Ethiopian capital Addis Ababa to the port city of Djibouti via Dire Dawa and Dewele. This will be the fourth international fibre link between Ethiopia and Djibouti, following the inauguration of two cross-border fibre links via Dewele and one via Galafi.

Zayo Group Holdings has revealed plans to build an additional fibre-optic network infrastructure in the state of Ohio (US). The new network cable will add almost 300 route miles in the Youngstown and Akron areas, with an anchor customer for the upcoming new cable already secured. The new metro infrastructure, expected to be fully installed in 2020, will complement Zayo’s existing long-haul connectivity through the Cleveland-Akron-Pittsburgh corridor. Steve Orlando, senior vice president of Central Region at Zayo, said: ‘The expanded metro fibre routes will strengthen and expand our footprint to approximately 3,500 route miles, including connections to multiple on-net buildings and data centres in Cleveland, Cincinnati, Columbus, and Toledo.’
