We are about to place a duct for fibre internet to be pulled to the farm. Unfortunately when I dig the duct the old farm copper line will be destroyed. With copper phone lines going soon, what cable would be best to reconnect and would it be useful to transmit internet back up the track if we wanted to control a gate or camera at the entrance. Distance is about half a mile. I dare not put ducting too far from the track or I will surely cut it with subsoil or mole.
