As diode lasers are semiconductor devices, they may also be classified as semiconductor lasers. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectivel.

NEC announced today the successful completion of the Kochi-Lakshadweep Islands Submarine Cable (KLI) optical submarine cable system in Southern India connecting Kochi and 11 Lakshadweep islands. Chinese telecom giant FiberHome has reached mass production for a record-breaking 13,824-core optical cable. This breakthrough addresses critical space constraints in urban infrastructure and bolsters China's domestic supply chain for AI and 5G/6G development. NEC, as one of the top three enterprises in the submarine cable market, succeeded in prototyping the world's first four-core optical fiber submarine cable in July 2022. In this press release, we announce the success of our transoceanic long-distance transmission experiment over 7,280 km using. Achieved using a newly developed standard 19-core optical fiber, equivalent to 19 standard fibers, low loss across multiple wavelength bands, and the development of an optical amplification relay function compatible with this fiber. The FOA created its Online Reference Guide to provide a more up-to-date and unbiased reference for those seeking information on cabling and fiber optic technology, components, applications and installation.

The government of South Sudan on Thursday commissioned a $38 million upgraded power distribution system financed by the African Development Bank to restore reliable electricity supply to Juba's central business district and boost suburban livelihoods. The proposed operation is a supplementary financing in the form of a loan of UA 10. The South Sudan–Uganda Power Interconnection Project (SUPIP) is a transformative regional energy infrastructure initiative to be implemented by the Governments of South Sudan and Uganda, with coordination by the Nile Equatorial Lakes Subsidiary Action Program Coordinaion Unit (NELSAP-CU). ESMAP is a partnership between the World Bank and 24 partners to help low- and middle-income countries reduce poverty and boost growth through sustainable energy solutions. In 2020, the World Bank, in response to South Sudan's transitional government's request, set up the Pathways to Electricity Access Expansion in South Sudan project.

In 2024, over 15 submarine cables encircle Africa, with new projects like Google's Equiano and Meta's 2Africa added thousands of terabits of capacity, dramatically increasing internet speeds and reliability. Though tech giants have invested heavily in high-performance digital infrastructure — more cell towers, faster networks — Africans across the continent still grapple with sluggish internet speeds and expensive data. Tech companies such as Google and Facebook parent Meta are investing in new data. Bayobab, a subsidiary of MTN Group, has announced a collaboration with Africa50 to build a terrestrial fibre optic cable network that would run across Africa. Called Project East2West and riding on a $320 million investment, the project aims to connect the eastern and western shores of Africa. Africa's rapid digital transformation is reshaping the continent's economic landscape, driven largely by ambitious fibre-optic projects, submarine cables, and national broadband networks.

The Amilcar Cabral IT cable project aims to connect Cabo Verde, The Gambia, Guinea, Guinea-Bissau, Liberia, and Sierra Leone through a submarine cable network. While submarine communications cables are used to connect countries and continents to the Internet, terrestrial fibre optic cables are used to extend this connectivity to landlocked countries or to urban centers within a country. The objectives of the project are to enhance international telecommunications capacity, improve access to digital services and provide. Orange announced the commissioning and commercial launch of Djoliba, the first pan-African backbone network, covering 8 countries: Burkina Faso, Côte d'Ivoire, Ghana, Guinea, Liberia, Mali, Nigeria and Senegal.
