Abstract: A networking system includes a pluggable security device comprising at least one port interface that is insertable into at least one physical port, memory that stores a security key used to provide security over a network link, and processing circuitry coupled with the at least one port interface and with the memory. The processing circuitry utilizes the security key to verify security of a point-to-point connection established over the network link and after verifying the security of the point-to-point connection, provides a data integrity check function for data packets received at the at least one port interface.

Abstract: Apparatuses, systems, and methods are described that provide improved networking communication systems and associated adapters. An example networking communication adapter includes an adapter housing defining a first end and a second end opposite the first end. The first end is configured to engage an Octal Small Form Factor Pluggable (OSFP) connector, and the second end is configured to receive a Quad Small Form Factor Pluggable Double Density (QSFP-DD) transceiver therein. The networking communication adapter further includes an inner connector positioned within the adapter housing. In an operational configuration in which the first end engages the OSFP connector and the second end receives the QSFP-DD transceiver, the inner connector operably connects the QSFP-DD transceiver with the OSFP connector such that signals may pass therebetween.
