Tunisian state-backed operator Tunisie Telecom (TT) has secured a US$ 106.1 million loan from the European Investment Bank (EIB) to help fund the expansion and development of its infrastructure. In a statement, TT said it would use the funds to bankroll the deployment of 1,500 4G sites and 2,000km of fibre-optic cabling. Further, the operator said it would also upgrade its backbone network with Coarse Wavelength Division Multiplexing (CWDM) technology to cope with the rising demand for high speed connections.
