Orange is set to construct a new terrestrial fiber optic network in West Africa. The infrastructure will be coupled with submarine cables and will be centrally managed, with the commercial launch planned for mid-2020. Orange says the multi-regional West African network will connect to the rest of the world through various submarine cables, and will link the main capital cities in the region including Dakar, Bamako, Abidjan, Accra and Lagos. The network will be in addition to Orange’s recent investment in the MainOne submarine cable between Senegal and Côte d’Ivoire to Europe. The new network is designed to provide large-scale, international capacity and will help meet business needs and develop a digitalecosysteminWestAfrica. Itwill support a range of international connectivity services, including international private line and ethernet private line services with bandwidths of up to 100G ps.

NAI in Suzhou, China, has begun the development and manufacture of highly complex cable harnesses for installation within large, explosion-proof enclosures. The cabinets are placed within mines for the operation and control of variable frequency drives and inverters that power conveyor belts, water and oil pumps, cooling fans, tape winding devices and brakes inside the mines. They also provide alerts and notifications for transformers, motors, cables and other components when they are not operating within set parameters such as temperature or voltage range. The operational drives use NAI interconnect solutions for the transmission of control signals. Ten different cable harnesses have been designed for data communications and control, some with shielding for protection against EMI. A typical data/control harness has over 100 terminations, with the largest harness needing more than 900 terminations. New harnesses carrying power are in the planning and design stages.
