State-backed full service provider Empresa de Telecomunicaciones de Bogota (ETB) has rolled out fibre-optic rings in the cities of Medellin and Bucaramanga as part of a regional development programme, TeleSemana reports. Under the project, ETB also intends to install fibre networks in Cali, Cartagena, Barranquilla and Tunja over the course of 2014 and 2015. The new networks will allow ETB to offer additional services such as data transport solutions and dedicated internet connections, which are expected to help the telco meet its goal of generating 30% of its revenue from outside Bogota, its main operating area, by 2020.
