The Federal Aviation Administration (FAA) has completed the activation of a new fiber optic communications network supporting air traffic control at Newark Liberty International Airport in New Jersey. The upgrade was announced Thursday by U.S. Secretary of Transportation Sean Duffy.
The new network replaces aging infrastructure that had been associated with multiple telecommunications failures in recent months. These failures contributed to air traffic delays and temporary reductions in the airport’s operational capacity, prompting calls from airline and industry groups for federal action.
The FAA laid the fiber optic cables in June and conducted system testing throughout the past month before transitioning to the new network early Thursday morning. Officials say the fiber optic system is expected to reduce the risk of future disruptions and improve the overall reliability of air traffic communications at Newark.

“This marks a critical milestone in our work to make flying safer and more efficient at Newark Airport,” Duffy said in a social media statement.
The airport has experienced a series of operational challenges in recent months, including airspace congestion and staffing shortages, in addition to the recent telecommunications breakdowns.
