Abstract: A method in which a plurality of transmit signals are generated at data rates that are offset from each other by inserting an idle data block into a data stream for one or more transmit signals of the plurality of transmit signals to increase a data rate for the one or more transmit signals, thereby minimizing detectable electromagnetic interference at a particular frequency. The method further includes converting each transmit signal of the plurality of transmit signals to a corresponding optical transmit signal of a plurality of optical transmit signals for transmission via a corresponding channel of a plurality of channels of an optical network device and transmitting the plurality of optical transmit signals via respective ones of the plurality of channels for transmission on respective optical fibers.

Abstract: In one embodiment, an apparatus includes a plurality of optical module ports in communication with a physical layer device in a network device. Communication of signals from the physical layer device to the optical module ports is configured such that the signals received at the optical module ports adjacent to one another are at different phases to reduce electromagnetic interference associated with the optical module ports.

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.

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.
