Telecom contractor Bob Sellenriek recently bought three massive bulldozers and fitted them with cable-burying plows that had been gathering dust in his warehouse for a decade.
Mr. Sellenriek needed the plows for something he has done very little of since the telecom bubble burst and wiped out $2 trillion in stock market wealth more than 10 years ago: laying miles of new fiber-optic cable. After years of licking its wounds, and with much of the fiber-optic cable capacity in the ground still unused, the telecom industry is going on another building spree.
