OFIS is a state-of-the-art system that combines IP Audio TM technology and fiber optics for highways and tunnels. OFIS is usually connected to a control center and/or emergency breakdown services. Auto-dial on the handset lifter is often used to connect users directly to the remote control center for appropriate response in every situation, or point-to-point communication via keypad for routine maintenance inspection personnel.
The OFIS system can support a general or group search via the main console of the control room, even very complex, by combining the appropriate elements, such as an additional siren / loudspeaker or a warning light. The OFIS system device supports optical fiber network.
Modern road infrastructures use optimized control methods and increased automation to improve supervision while reducing costs. Using fiber optics for reliable communications and to monitor, analyze and control equipment and facilities has been proven to improve efficiency. Fiber optic networks are therefore used to manage, control and interconnect a wide range of communication technologies by wired or wireless intercom solutions based on wifi.
