This Araknis Networks® QSFP28 Transceiver Module is optimized for use with the Araknis switches that feature a QSFP28 port. For example, AN-920 switches with an Araknis Network QSFP28 100Gbps Expansion Module (AN-SFP-100G-10). It is available in 1m or 3m options with Passive Copper DAC (Direct Attach Cable), and is designed for server racks that require high-speed data transfer capabilities over shorter distances. With pull-to-release latches on the connectors, swapping out ports becomes quick and easy when working with server racks.
