ABSTRACT:
An apparatus/system for use in coupling power from a power supply to a device over a network transmission medium is provided. The coupling apparatus/system generally includes one or more common mode chokes that feature a first winding and a second winding, the first winding being electrically connected between the first terminal of the power supply and the first electrical conductor of the network transmission medium, and the second winding being coupled between the first terminal of the power supply and the first electrical conductor of the network transmission medium. The common mode choke generally includes at least one core for coupling the first and second windings of the one or more common mode chokes. An RJ45 to 110 IDC modular connector may be connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to help reduce near-end crosstalk (NEXT) without compromising impedance. DC power is coupled upon the signal line by utilizing a wideband high impedance common mode choke design.
