Build cleaner 100 GbE interconnects with this NVIDIA Mellanox compatible QSFP28 direct-attach copper cable. The 2 m length is tuned for short server-to-switch and switch-to-switch runs, where passive copper is often the most practical choice. It keeps the link direct, avoids the added cost of optical transceivers, and reduces the number of components your team has to source, track, and support. In dense infrastructure, cable length matters. A shorter DAC helps preserve signal quality while improving airflow and rack organization. The QSFP28-to-QSFP28 interface supports modern 100GBASE-CU and InfiniBand deployments, making it a straightforward fit for high-bandwidth fabrics that do not need optical reach. This model also supports procurement discipline. Its TAA-compliant status makes it suitable for environments with sourcing requirements, while the passive copper design helps control both power and budget. Choose the 2 m version when your topology calls for a precise, short run and you want the reliability of a direct physical connection without paying for unused optical capability.
