As Frontier Communications emerged from chapter 11 bankruptcy on Friday, officials with the Norwalk-based telecommunication company made it clear they expect high-speed internet service — delivered by fiber optic cable — to deliver them from the financial wilderness, the New Haven (Conn.) Register reported. “The focus is on fiber,” said John Stratton, the incoming executive chairman of the board for Frontier, which saw its executive team undergo a dramatic reorganization during the full year it was under chapter 11 bankruptcy protection. “The goal is to replace our existing copper network with fiber.” Stratton and other Frontier executives explained the company’s strategy during a call with financial analysts reporting on its first quarter earnings. The company had earnings of $60 million in the three-month period that ended March 31 — a dramatic reversal from the same period in 2020, when the company lost $186 million.
