BlueLAN SC282801L0.5M30 100G QSFP28 Direct Attach Cable, 0.5 m, Passive Copper, Infiniband EDR, Dell 470-ABPW Compatible 470-ABPW-BL

This BlueLAN direct attach cable delivers 100 Gbps over a short 0.5-meter link, making it a practical choice for dense rack connections where latency and power draw matter. Unlike optical transceivers that require separate modules, this passive copper assembly integrates QSFP28 connectors on both ends, eliminating the need for additional optics and reducing the overall cost per port.

Highlights

• 100GBASE-CR4 Ethernet and Infiniband EDR support
• QSFP28 to QSFP28 connectors, 30 AWG passive copper
• 0.5 m length for top-of-rack and adjacent server links
• Hot-swappable with power consumption below 0.5 W
• Compatible with Dell 470-ABPW and equivalent ports

In daily use

The cable is engineered for data center environments where short-reach, high-bandwidth links are common. Its passive design means no active components, so it adds no measurable latency and consumes minimal power. The 30 AWG conductors keep the cable flexible for easy routing in tight spaces, while the PVC jacket provides durability. Operating temperature range spans 0°C to 70°C, covering typical server room conditions.
