The PRS-FIN, PRS-FINNA, and PRS-FINS fiber interfaces connect glass fiber optic cable to plastic fiber optic cable within Praesideo communication systems. They convert between the cable types and support redundant network connections. Each interface provides power and status indicators and includes two control inputs, except for the PRS-FINNA which lacks a network address and control inputs.
