There is a large number of civil aviation air traffic control terminal equipment. When the equipment fails to maintain, the space is narrow and easy to cause other faults, which may cause certain interference to the controller's command when handling on- site faults. The above problems can be avoided by sinking the control terminal equipment with optical fiber matrix technology. The new air traffic control room has been used in some areas. This paper mainly discusses how to design and use optical fiber matrix equipment to sink the control terminal equipment and ensure the safety and reliability of the control and operation equipment.
