BlueLAN 470-AAGI-BL Compatible Dell QSFP+ Direct Attach Copper Cable, 40GBASE-CR4, 30 m, Active, Twinax, Ethernet/InfiniBand QDR

This BlueLAN 470-AAGI-BL is a 30-meter active QSFP+ direct attach copper cable engineered for 40GBASE-CR4 Ethernet and InfiniBand QDR links. Unlike shorter passive DACs that rely on host equalization, its active signal conditioning sustains full 40 Gbps over the full 30 m reach—ideal for top-of-rack to end-of-row connections in dense data centers.

Highlights

• 40 Gbps aggregate bandwidth over four 10 Gbps lanes
• QSFP+ to QSFP+ connectors, hot-swappable
• Active twinax construction with integrated signal amplification
• Compatible with Dell 470-AAGI and equivalent QSFP+ ports
• Supports 40GBASE-CR4 Ethernet and InfiniBand QDR protocols

In daily use

The cable's 30-meter length bridges aggregation switches and access rows without the cost or power draw of optical transceivers. Its PVC jacket and 100-ohm impedance maintain signal integrity across the operating range of 0°C to 70°C, while power consumption stays below 1.5 W. The hot-swappable QSFP+ ends simplify moves and changes in high-density racks.
