Liquid Telecom, a subsidiary of Zimbabwe’s largest cellco in terms of subscribers Econet Wireless, has upgraded its fibre-optic network across South Africa, Zimbabwe and Zambia to support dense wavelength division multiplexing (DWDM) transmission technology. According to a press release, the DWDM technology is capable of carrying multiple 10Gbps wavelengths and can scale to support speeds of up to 100Gbps, thus providing more resilient transmission architecture. Liquid Telecom’s managing director Wellington Makamure said that the technology will provide both Zimbabwe’s and Zambia’s broadband markets with high capacity access to undersea cables that link Southern Africa to the rest of the world. The executive clarified: ‘The high-speed technology goes across the borders into South Africa through Johannesburg to link two data centres – Teraco and Neotel. These two data centres are in turn linked to five undersea cables, namely SEACOM, WACS, EASSY, SAT-3 and TEAMS.’
