Public Safety Data Network


The Public Safety Data Network (PSDN) is an ultra-high-speed fiber optic data network that serves as a dedicated transport infrastructure and interconnectivity pathway for public safety and government applications and services throughout the state. The network consists of approximately 8,800 miles of dark fiber connecting 515 nodes or Points of Interest (POIs) and is designed with the highest level of redundancy. This network connects the 110 Public Safety Answering Points (PSAPs) in Connecticut that provide the 911 Emergency Answering service to the residents of the state. This network also interconnects all State Police and local police departments and provides connectivity to centralized criminal information systems such as NCIC, NLETS and AFIS. The ENS group supports this infrastructure exclusively.
