Product Description
00G QSFP-DD Passive Direct Attach Copper Cable (DAC) for Data Center Networking & High-Performance Computing
 
Description QSFP-DD (Quad Small Form-factor Pluggable Double Density) passive copper direct-attach cables provide a cost-efficient solution for establishing 400-Gigabit connections between QSFP-DD ports in data center environments. Designed exclusively for short-reach deployments, these cables offer high-density connectivity and exceptional performance within strict distance limits. Compliant with industry-standard protocols, they ensure seamless integration into high-speed networking infrastructures, ideal for space-constrained racks and low-latency applications.
