  • Circuit for realizing passivation of intelligent optical distribution interface disc in machine disc enable manner
    Patent number: 9608737
    Abstract: Disclosed is a circuit for realizing passivation of an intelligent optical distribution interface disc in a machine disc enable manner, which relates to the field of optical communications. In the present invention, a distribution port is separated from distribution management, all management circuits on a distribution interface disc are moved out, and all control and management functions are achieved on a distribution management disc, to enable passivation of a distribution interface disc circuit, i.e. any active electronic devices such as integrated circuits, triodes, etc. which are easily damaged by static electricity and affected by fouling are not placed on the distribution interface disc any longer, and power lines are not introduced in the distribution interface disc.
    Type: Grant
