Abstract: An electrical device includes a core structure having a first core section, a second core section, and a third core section. The electrical device further includes a first coil electrically coupled to the first core section and the second core section to form a choke and a primary winding of a transformer. The choke is configured to reduce common mode noise for an electrical signal received by the electrical device, and the primary winding of the transformer is configured to induce a magnetic field on the third core section. The electrical device also includes a second coil electrically coupled to the third core section, which forms a secondary winding of the transformer and receives electromagnetic energy from the magnetic field induced by the primary winding of the transformer.

Abstract: In one embodiment, an apparatus includes an array of transformers and common mode chokes each comprising a magnetic core and windings wound around the magnetic core at opposing locations on the magnetic core, and a retaining groove on each of the magnetic cores to maintain the windings in their opposing locations on the magnetic core. The transformers and common mode chokes are positioned in the array with the windings on each of the magnetic cores located offset to the windings of adjacent magnetic cores in the array to reduce crosstalk and improve common mode noise rejection.

Abstract: An electromagnetic interference (EMI) shielding apparatus includes a cage structure having an opening at a first end and a second end opposite to first end. The cage structure is configured to contain one or more electrical components that emit electromagnetic energy and a connector for the one or more electrical components. The first end is configured to receive a pluggable module that is to connect to the one or more electrical components. The EMI shielding apparatus further includes a filler assembly disposed in the opening. The filler assembly is biased to close the opening of the cage structure when a pluggable module is not inserted/plugged in the opening.

Abstract: In some implementations, a method includes analyzing an amount of data communicated by a set of network interfaces. The data communicated by the set of network interfaces is processed by a set of functional units and a set of queues includes the data communicated by the set of network interfaces. The method also includes activating a first functional unit of the set of functional units when a first size of a first queue of the set of queues is above a first threshold. The method further includes deactivating the first functional unit of the set of functional units when the first size of the first queue of the set of queues is below a second threshold. The method further includes causing the data to be forward to one or more active functional units via a data interconnect coupled to the set of network interfaces and the set of functional units.
