Keep short-reach 100G links clean, direct, and cost-controlled with this Cisco-compatible QSFP-DD DAC cable from AddOn Networks. Designed for tightly packed data center racks, the 2.5 m passive copper assembly delivers a straightforward path between adjacent switches, top-of-rack gear, and high-density aggregation layers without the added cost or power draw of optics. For infrastructure teams standardizing on direct attach cabling, this cable supports fast deployment and consistent physical-layer performance in environments where link distance is known in advance. The fixed 2.5 m length helps reduce slack management issues while preserving a tidy rack layout. It is a practical choice for short interconnects that still demand dependable throughput and vendor-compatible fit. This cable is well suited for procurement teams looking to extend the life of existing Cisco-aligned infrastructure with a qualified third-party alternative. It offers the simplicity of passive copper for short runs, making it a strong fit for budget-conscious upgrades where optical transceivers would add unnecessary cost and complexity.
