One of the key conclusions of the study was that the cost of direct buried duct
— plastic tubing into which optical fibres can be blown as and when required —
was lower than that of direct buried cable when considered over a 25 year
period, even though the upfront costs were higher. The study took into account
events such as adding subscribers, maintenance and repairs.
Another step in the right direction. Still, investors need to be convinced to take a long-term view.
