Dell 3.3ft QSFP+ to QSFP+ 40GbE Passive Copper Direct Attach Cable

The Dell 470-AAVR is a QSFP+ to QSFP+ direct attach cable that spans 3.3 feet and carries data at forty gigabits per second. It gives network teams a simple way to connect devices positioned within the same rack or on adjoining racks, avoiding the extra cost and power draw that come with optical transceivers.

This cable uses twinax copper conductors that keep signal integrity high while keeping power demands low. The passive design means there are no active components in the link, so installation is as easy as inserting each end into a compatible QSFP+ port and locking the tabs. With minimal crosstalk and a low bit-error rate, it maintains consistent performance even in busy data paths.

Systems engineers will find the Dell 470-AAVR helpful for top-of-rack switch links, server clustering, or high-speed storage connections where the distance is short and throughput is critical. Its plug-and-play nature makes it a practical choice for data centers, enterprise labs, or small offices that need reliable forty-gigabit connectivity without added complexity.
