With only two major highways running down the west side of Taiwan, congestion and long traffic jams during holidays and long weekends is a certainty. The Taiwan National Highway Bureau (TNH) has set up several traffic monitors and control centers to monitor traffic and to provide drivers with road conditions and alternative routes for bypassing congested sections. To obtain real-time highway road conditions, the control centers rely on a large number of cameras installed along the highway. Most cameras support zoom-in/zoomout and left/right panning operations powered by a motor that is controlled remotely over an RS-485 connection. By taking advantage of existing fiber cables that run the length of the highway, system engineers used serial-to-fiber converters to control camera motors from the control center.

Serial-to-fiber converters are generally used in pairs, and Moxa provides both standalone products and chassis solutions for high density media systems. Available products include the ICF-1150 series, which is an industrial serial-to-fiber converter with a wide operating temperature of -40 to 85ºC. In addition, the NRack System chassis solution is used in the TNH's control center. The advantage of the NRack System is that slide-in modules can be plugged into the chassis to save valuable cabinet space and mounting effort.
