[0063] The mainboard input connection module is a component used to connect the fiber optic input card and the switching switch. In hardware, the mainboard input connection module usually includes a connector or a plug-in connector, which is used to connect the fiber optic input card and the input port of the switching switch to achieve signal transmission.
