Move 40 GbE traffic across short distances with a direct attach cable designed for practical infrastructure work. The AddOn 10323-AO is compatible with Extreme Networks 10323 and supports passive copper connectivity for QSFP+ to QSFP+ links, making it a strong fit where optical modules would add cost and complexity. This cable is built for environments that value predictable short-run performance, clean rack cabling, and procurement clarity. It is TAA compliant, programmed, uniquely serialized, and tested for data traffic and application functionality, which helps reduce deployment risk in enterprise and public sector environments. The 5.0 m reach gives teams enough flexibility for adjacent rack and row-level connections without moving to optics. For architects and procurement teams, the appeal is straightforward: fewer parts, less power overhead, and a cable that aligns with standard 40 GbE copper interconnect strategies. When the requirement is a dependable QSFP+ direct attach path, this model delivers the right balance of compatibility and operational simplicity.
