  • East Africa Optical Cable Project

    East Africa Optical Cable Project

    The EASSy project is an initiative to construct and operate a submarine fibre-optic cable along the east coast of Africa to connect 20 coastal and land-locked countries to each other and to the rest of the world. The project, with an estimated cost of USD 235 million, will run cable from Port. The launch of 2Africa enables us to offer our customers seamless connection between Africa and Europe, together with our SEA-ME-WE 5 and AAE-1 subsea cable resources to further extend to Asia, which is an important milestone of our global development strategy,” said Jessica Gu, Director & Chief. The project concerns the deployment of fibre optics networks in regions of Eastern Africa where, either these kinds of networks are not available, or they are expensive and unreliable. In both cases, the development of digital services enabled by broadband access is limited.

  • Tonga lays fiber optic cable

    Tonga lays fiber optic cable

    Tonga Cable System is a submarine fiber-optic cable system connecting Tonga with Fiji, where it connects to other international networks. It is 827 kilometres (514 mi) long and was activated in 2013. It has cable landing points at Sopu, a suburb of Nukuʻalofa in Tonga, and Suva, Fiji. The internet is kind of like drinking water, says UC Berkeley Professor Nicole. Before August 2013, Tonga had no submarine cable. A nation of 100,000 people spread across 170 islands in the South Pacific depended entirely on Intelsat satellite links for all international communications. A basic broadband. Repairs to Tonga's Domestic Cable system connecting Tongatapu to Ha'apai and Vava'u have finally been completed, 18 months on from the Hunga-Tonga Hunga-Ha'apai volcanic eruption that caused damage to the system. The residents of Vava'u and Ha'apai will continue experiencing phone and internet outages caused by the damaged submarine.

  • What type of cable is a single-strand fiber optic patch cord

    What type of cable is a single-strand fiber optic patch cord

    Simplex patch cord: A simplex patch cord only has a single fiber cable and one fiber connector at each end. As data rates increase from 10G → 100G → 400G → 800G, patch cables must handle more bandwidth, more density, and stricter. A fiber optic cable is a transmission medium that uses strands of glass or plastic fibers to carry data as pulses of light. It offers high bandwidth, low signal loss, and resistance to electromagnetic interference (EMI), making it ideal for modern high-speed networks. It is mainly used in applications such as optical fiber communication systems, optical fiber access networks, optical fiber data transmission networks, and local area networks.

  • Fiber optic cable mechanical joint connection

    Fiber optic cable mechanical joint connection

    Semi-permanent connections can be made with mechanical splices, which are relatively simple alignment devices holding the fiber ends together. Typically, some index-matching gel or an epoxy is used for reducing reflection losses. Examples are fiber lasers and systems for optical fiber communications. Mechanical splices are used to create permanent joints between two fibers by holding the fibers in an alignment fixture and reducing loss and reflectance with a transparent gel or optical adhesive between the fibers that matches the optical properties of the glass. Either joining method must have three primary characteristics. Optical fibers can be joined together, such that light is efficiently transferred from one fiber to another. That is usually done for permanent connections, but it.
