Abstract
An inductive coupler assembly for use in a downhole environment and related methods are described. An example indicative coupler assembly includes a first inductive coupler having first and second magnetically coupled coils and a second inductive coupler having third and fourth magnetically coupled coils. The first and third coils are coupled to a first pair of signal lines and the second and fourth coils are coupled to a second pair of signal lines. The first inductive coupler is to magnetically convey a differential communications signal between the first and second pairs of signal lines, and the second inductive coupler is to magnetically convey a common mode power signal between the first and second pairs of signal lines.
