Patent ID: 8680405

Claim:
A circuit board, comprising: a first path, routed on a first layer of the circuit board for transferring a first signal; a second path, routed on a second layer of the circuit board for transferring a second signal; a third path, routed on a third layer of the circuit board; a first via, coupled to the first and third paths, wherein the first via is removed when the second path is utilized to transmit the second signal; and a second via, coupled to the second and third paths, wherein the second via is removed when the first path is utilized to transmit the first signal; wherein the first path is used for coupling to a first interface component and the second path is used for coupling to a second interface component, wherein the first interface component transfers the first signal according to a first transport protocol and the second interface component transfers the second signal according to a second transport protocol, and wherein the first transport protocol is Serdes Framer Interface(SFI) and the second transport protocol is Serial Gigabit Media Independent Interface(SGM II).
