Abstract: A power over Ethernet (PoE) interface for 10GBase-T Ethernet includes at least one communication channel Ethernet interface including an autotransformer having a center tap for coupling direct current (DC) power. A combination of the geometry of the toroid core of the autotransformer and in some embodiments of a common mode choke, as well as the wire twisting, the wire distribution and the wire routing allow maximizing bandwidth up to or greater than 500 MHz for 10GBase-T performance by increasing the coupling and reducing capacitance across the wires, and results in return and insertion losses and OCL that meet anticipated standards.

Abstract: A connector is provided including at least one pair of contacts, at least one pair of terminals electrically coupled to the contacts by at least one pair of conductors, and a transient voltage suppression component electrically coupled to the contacts and the terminals. The transient voltage suppression component includes a transient voltage suppression device and a frequency compensation device. The frequency compensation device is coupled in series with the transient voltage suppression device and the transient voltage suppression component is coupling the pair of conductors. The frequency compensation device is an inductor. One of the transient voltage suppression device and one the frequency compensation device are used for each pair of conductors. Alternatively, two of the transient voltage suppression devices and two of the frequency compensation devices are used for each pair of conductors.
