Nigeria’s Globacom has signed a contract with Huawei to build a second fiber optic submarine cable that will run from Lagos to the southern part of Nigeria.

Per an article in This Day, the new cable, to be known as Glo2, is expected to be completed in the next 18 months. It will have 12 Terabit capacity per second and span 850 km, providing last-mile connectivity to businesses and oil companies in southern Nigeria and beyond.

Nigeria has several submarine cables berthed on its shores, but none has the capacity to provide broadband connectivity to the hinterlands, where there is high demand, the report said. “The situation has compelled telecoms subscribers to call for last-mile connectivity that could cushion the effect of the high cost of broadband bandwidth in the hinterlands, as well as the price differential in bandwidth between Lagos and the hinterlands. The Glo 2 optic fiber submarine cable is expected to address those challenges.”

The plan for the Glo 2 project was launched at a contract signing ceremony by Globacom and Huawei. Globacom’s regional director for technical affairs, Sanjib Roy, said the submarine cable would be built along the Nigerian coast from Alpha Beach in Lagos, where the Glo 1 landing station is located, to the Southern part of Nigeria. He said that the cable would contain three fiber pairs, with the first pair connecting Lagos directly to the southern part of Nigeria, with terrestrial extension to other parts of the country for redundancy and maintenance purposes. The second will be equipped with eight switchable Branching Units (BUs), which will deliver high capacity to offshore oil stations and communities connected directly to BUs, while the third pair will be equipped with two switchable branching units to deliver high capacity to Cameroon and Equatorial Guinea.

The facility will enable a high capacity connection in the south and provide capacity to offshore oil platforms and the communities. Roy said that the Glo 2 project would boost telecom service delivery in the country by providing economic and social capacity to communities in oil producing regions. It will also digitize oil platforms to improve productivity, upload data to remote oil platforms at the speed of light.

Glo2 complements the Glo 1 international submarine cable built by Globacom in 2010, which is the only international submarine cable in Nigeria managed end to end, from Lagos to London, by one company. It currently provides sufficient bandwidth for the West Africa sub-region.
