27 Aug 2021

Djibouti Telecom is leveraging Ciena’s GeoMesh Extreme solution to upgrade its Djibouti Africa Regional Express 1 (DARE1) network linking Djibouti (Djibouti), Bosaso (Somalia), Mogadishu (Somalia) and Mombasa (Kenya). Ciena’s GeoMesh Extreme submarine network solution utilises the 6500 Packet-Optical Platform powered by the WaveLogic family, allowing a doubling of line rates to 400Gbps. Ian Clarke, Vice President of Global Submarine Solutions at Ciena, commented: ‘Leveraging Ciena’s GeoMesh Extreme, Djibouti Telecom expands the capacity of DARE1 to make possible dynamic new 10G, 100G, and Spectrum Sharing services for an increasingly digital world.’ The USD80 million system – owned by Djibouti Telecom, Somtel, Hormuud Telecom and Telkom Kenya – was deployed by SubCom. The 4,854km DARE1 cable – which includes 41 dual-stage repeaters to maximise its capacity – is configured as a three-fibre pair trunk and each trunk fibre pair has cross sectional capacity of 40 channels at 300Gbps; in addition to the dual-stage repeaters included on all branches of the system, the Bosaso and Mogadishu segments are equipped with a switched ROADM, to provide flexible capacity routing and a robust fault protection scheme for the system. The system provides 36Tbps of capacity.

Lumen Technologies (formerly CenturyLink) and Stonepeak’s newly established holding company Patagonia Holdco have requested the Federal Communications Commission’s (FCC’s) consent to transfer control of Global Crossing Americas Solutions (GCAS), CenturyLink Latin American Solutions (CLAS) and Level 3 Communications St. Croix to Patagonia Holdco. In July 2021, Lumen Technologies inked a definitive agreement to sell its Latin American business to New York-based alternative investment firm Stonepeak, in a deal worth USD2.735 billion. AustralianSuper, Australia’s largest pension fund, will act as a co-investor, alongside Stonepeak. Under the terms of the purchase agreement, Lumen will divest its Latin American business, which will operate as an independent, US-headquartered portfolio company of Stonepeak. The assets in question were acquired by CenturyLink in 2017, as part of its buyout of Level 3.

Sparkle and Panama-based Trans Ocean Network have agreed to form a strategic joint venture in Panama for the construction of an open landing and connectivity centre. Located in Panama City, the new building will offer 3,200 square metres of colocation space for over 600 racks. The Panama Digital Gateway will be integrated with Sparkle’s global backbone – more than 600,000km of fibre spanning from Europe to Africa, the Americas and Asia – and will also be the landing point of existing and upcoming submarine cables looking for a diversified entry way to Central America. By establishing a presence in the new hub, OTTs, carriers, financial institutions and corporations will be able to benefit from Sparkle’s global connectivity services – including its global Tier-1 IP transit service Seabone and its capacity solutions – and access to other regional networks.

Liquid Intelligent Technologies (LIT) has established a direct access to US via a new PoP connection to Miami. As part of Liquid’s East-West route between the US and Asia via Africa, the new PoP is connected to LIT’s 100,000km of fibre across eleven countries on the continent and another 14 countries via the Operators Alliance Programme and Liquid Satellite Services. Liquid will connect to Miami via Fortaleza in Brazil and Luanda in Angola via the South Atlantic Cable System (SACS) and Monet submarine cables. The PoP will be hosted at the Equinix data centre in Miami. LIT can already provide access to all data centres and millions of destinations in North America through its partnership with Zayo.
