Google has revealed that the deployment of the Curie submarine cable network linking Chile with the US has been completed with the landing of the submarine cable in the Playa Ancha area in the Valparaiso Region of Chile. The four-fibre pair system, deployed by SubCom, spans over 10,476km and links Los Angeles (US) to Valparaiso (Chile), and includes a branching unit for future connectivity to Panama. The California landing will leverage the Equinix LA4 International Business Exchange (IBX) data centre in El Segundo. Chris Carobene, vice president of marine services and network construction at SubCom, said: ‘Google and SubCom’s consistent teamwork allowed for mitigation of potential risks to the Curie cable system project schedule, enabling early completion of the Valparaiso landing.’ Google did not reveal when it expects the system to be operational.

Keir Preedy, CEO of Solomon Submarine Cable (SSC), has revealed that the Ile de Brehat vessel scheduled to deliver the Coral Sea Cable System (CSCS) and the Solomon Islands Domestic Network (SIDN) is making its way to the Pacific, the Solomon Islands Broadcasting Corporation (SIBC) writes. The 4,700km subsea network will connect Sydney (Australia) to Port Moresby (PNG) and Honiara in the Solomon Islands. The four fibre-pair international system will deliver a minimum of 20Tbps capacity to Papua New Guinea (PNG) and the Solomon Islands respectively, bringing a total capacity of 40Tbps. The 730km domestic submarine cable system SIDN, meanwhile, will connect Honiara to Auki (Malaita Island), Noro (New Georgia Island) and Taro Island. The ship will first head to Port Moresby and lay the PNG branch of the CSCS cable from 6 June, heading to Honiara by 20 June to commence the deployment of the Solomon Islands branch. The executive added that the Solomon Island cable branch will be deployed to meet the PNG branch, with the ship then set to lay the combined CSCS cable down to Sydney in early August. Following the completion of the CSCS system, the Ile de Batz vessel will return to Honiara to commence the laying of SIDN at the end of August. As previously reported by TeleGeography’s Cable Compendium, in July 2018 Australia’s Vocus Group enlisted Alcatel Submarine Networks (ASN) to build the 4,000km CSCS cable. The AUD137 million (USD101 million) cable project – awarded to Vocus by the Australian government in June – is expected to be completed by late-2019.

Azerbaijan’s Azertelecom has launched a project for the construction of a fibre-optic cable line between Azerbaijan and Kazakhstan, Caspian News writes. To that end Azertelecom signed an agreement with Transtelecom and KazTransCom to establish a consortium to deploy the 400km cable along the bottom of the Caspian Sea, as part of the Trans-Eurasian Information Super Highway (TASIM) backbone project. As noted by TeleGeography’s Cable Compendium, a preliminary memorandum of understanding (MoU) regarding the implementation of the TASIM system was signed in Baku, Azerbaijan in December 2013, by China Telecom (China), KazTransCom (Kazakhstan), Rostelecom (Russia), Turk Telekom (Turkey) and Azerbaijan’s Ministry of Communications and High Technologies (MCHT). When finalised, the backbone network will connect 20 countries via two alternative routes – Southern and Northern – stretching from Frankfurt (Germany) to Hong Kong.

Infinera has supplied its XTC platform to Indonesia’s XL Axiata, in collaboration with Infinera’s local partner Lintas Teknologi. The Asian service provider will use the platforms to upgrade its terrestrial fibre network in South Sumatra as well as its capacity on the Jakarta-Bangka-Batam-Singapore (B2JS) submarine network that connects Jakarta (Indonesia) and Singapore. B2JS is a high-speed submarine cable system with 24 cores and 380Gbps of capacity. The Jakarta-Batam sub-section comprises 723km of submarine cable and 293km of terrestrial cabling, while the Batam-Singapore sub-section comprises 36km of submarine cabling and 18km of terrestrial routes. Yessie Dianty Yosetya, CTO at XL Axiata, commented: ‘The performance of Infinera’s ICE4 solution for this subsea and terrestrial network upgrade enables the delivery of cloud-scale capacity that is simple and operationally efficient, with the benefit of intelligent Optical Transport Network (OTN) switching that accelerates our ability to deliver services faster.’

Internet users in Bangladesh are likely to experience slow connectivity due to a scheduled maintenance of the SeaMeWe-4 submarine cable. The Bangladesh Submarine Cable Company Limited (BSCC) highlighted that the maintenance work will involve replacement of some infrastructure at the Cox Bazar’s landing station, which will be completed by 1 May. In the meantime, traffic will be rerouted through SeaMeWe-5 and terrestrial links.

Lastly, regional fibre broadband company Horizon Network Partners has agreed to buy 1,000 fibre miles of new infrastructure in downtown Indianapolis (US). Horizon expects to close the deal within 30 days, subject to the usual closing conditions. Horizon currently offers services in Ohio, Indiana, West Virginia, Pennsylvania, Kentucky, Michigan and New York via a 4,500-route-mile fibre-optic network.
