Network device and base pin distribution method thereof

The invention discloses a network device which comprises a line card and a network plate, wherein the line card and the network plate are arranged on a back plate in an orthogonal structure. Effective gap between a TX base pin and an RX base pin is n times bigger than an ordinary gap, wherein the TX base pin and the RX base pin are adjacent to each other and arranged on a signal interface of the line card. Effective gap between corresponding adjacent base pins of a TX base pin and a RX base pin which are adjacent to each other, arranged on a signal interface of the network plate and projected orthogonally on the signal interface of the line card is n times bigger than an ordinary gap. Effective gap between the TX base pin and the RX base pin which are adjacent to each other and arranged on a signal interface of the network plate is n times bigger than an ordinary gap. Effective gap between corresponding adjacent base pins of a TX base pin and a RX base pin which are adjacent to each other, arranged on the sig
