Fortinet FNCABLE-QSFPDD-DACB5 400 GE Passive DAC 2.5 m | QSFP-DD, 400G

Keep short-reach 400 GE connections simple and predictable with this Fortinet passive DAC. Designed for systems with QSFP-DD slots, the 2.5 m cable supports direct attach connectivity without the added cost and power draw of separate optics. That makes it a strong fit for top-of-rack and adjacent-rack deployments where latency, thermal load, and cable management all affect operational efficiency. Passive DACs are often chosen when teams want the most direct path between compatible ports. This model is built for that role: short, fixed-length, and purpose-made for high-density infrastructure where every port and every watt counts. It helps reduce component count, simplifies procurement, and keeps the signal path straightforward for tightly controlled data center layouts. For environments standardizing on QSFP-DD-based 400 GE switching, this cable offers a clean way to connect supported equipment with minimal overhead. It is a focused interconnect for teams that value deterministic short-run performance and a tidy physical layer.
