There is provided an inductive coupler for coupling a data signal to a
power line. The inductive coupler includes a split magnetic core having
an aperture formed by an upper magnetic core and a lower magnetic core.
The aperture permits the power line to pass therethrough as a primary
winding, the upper magnetic core is for making electrical contact with an
outer surface of the power line, and the lower magnetic core makes
electrical contact with the upper magnetic core.
