Miles of copper is ruined not only in the cable vault at Broad Street, but also at 20 or so manholes around the area. Even worse, paper insulation in the copper wiring sucks water through the cabling from capillary action, destroying cabling even in dry areas. Levendos says it’s “far too tedious, time consuming, and not effective of a process to try and put this infrastructure back together,” so Verizon’s taking the opportunity to rewire with fiber optics instead. Service has been restored to FiOS customers for over a week — unlike copper, fiber optics aren’t damaged by the water. As part of this process, crews have already pulled fiber up the major corridors — including Water, Broad, and Pearl Streets — to ultimately connect the fiber network to buildings.
