Abstract: The technology of microwave has been used widely in the domains of communication and others. And the HPMW (High Power Microwave Weapon) has been already used in the military. How to increase the ability of electronic equipment protection in the worse electromagnetic environment becomes an important subject task. Based on the needs of anti-HPM application, this paper designs an interface of PS/2 based on optical fiber transmission, and the related circuit in the design is presented. Experimental results show that this solution can well satisfy the requirement of optical fiber transmission and the protection of HPM. This solution has good prospects of application.
