Abstract
Aspects of the subject disclosure may include, for example, a substrate, comprising a first layer, a second layer, and an intermediary layer between the first layer and the second layer, a first pair of traces positioned in the first layer, a second pair of traces positioned in the second layer, and a jumper configuration at least partially defined in the intermediary layer, wherein the jumper configuration comprises a pair of vias that are configured for coupling the first pair of traces and the second pair of traces and for providing common mode rejection (CMR) filtering between first signals on the first pair of traces and second signals on the second pair of traces. Other embodiments are disclosed.

A substrate, comprising:
- a first layer, a second layer, and an intermediary layer between the first layer and the second layer;
- a first pair of traces positioned in the first layer;
- a second pair of traces positioned in the second layer;
- and
- a jumper configuration at least partially defined in the intermediary layer, wherein the jumper configuration comprises a pair of vias that are configured for coupling the first pair of traces and the second pair of traces and for providing common mode rejection (CMR) filtering between first signals on the first pair of traces and second signals on the second pair of traces.
An apparatus, comprising:
- first and second components of a communications system;
- and
- a substrate that interconnects the first and second components, the substrate having
- a first layer, a second layer, and an intermediary layer between the first layer and the second layer,
- a first pair of traces positioned in the first layer,
- a second pair of traces positioned in the second layer,
- a third pair of traces positioned in the first layer, and
- a jumper configuration at least partially defined in the intermediary layer, wherein the jumper configuration comprises a first pair of vias for coupling the first pair of traces and the second pair of traces and a second pair of vias for coupling the second pair of traces and the third pair of traces.
A method, comprising:
- identifying a portion of an intermediary layer of a substrate for implementing a jumper configuration,
- wherein the intermediary layer is disposed between a first layer of the substrate and a second layer of the substrate,
- wherein a first pair of traces is positioned in the first layer, and
- wherein a second pair of traces is positioned in the second layer;
- and
- at least partially defining the jumper configuration in the portion of the intermediary layer, wherein the jumper configuration comprises a pair of vias for coupling the first pair of traces and the second pair of traces and for providing common mode rejection (CMR) filtering between first signals on the first pair of traces and second signals on the second pair of traces.
