BlueLAN 40G QSFP+ to 4x10G SFP+ Passive Direct Attach Breakout Cable, 2m, 30 AWG, Dell Compatible CBL-QSFP-4x10GSFP-PASS-2M-BL

This BlueLAN passive direct attach breakout cable splits a single 40GbE QSFP+ port into four independent 10GbE SFP+ links, enabling high-density connections between switches, servers and storage without the cost and power draw of optical transceivers. The 2-meter length and 30 AWG copper construction keep signal integrity high while remaining flexible enough for tidy rack routing.

Highlights

• QSFP+ to 4x SFP+ breakout configuration
• Passive copper design – ultra-low power consumption
• Aggregate data rate: 40 Gbps (4 × 10 Gbps)
• 30 AWG wire gauge for optimal signal over 2 m
• Compatible with Dell and MSA-compliant ports
• Hot-swappable for easy installation

In daily use

The cable connects directly from a 40G QSFP+ port to four separate 10G SFP+ ports, eliminating the need for a breakout panel or active optics. Because it is passive, it adds no latency and consumes no power beyond the port itself. The 2-meter reach suits top-of-rack to adjacent rack links, and the 30 AWG conductors balance flexibility with performance. Operating temperature range is 0 °C to 70 °C, covering typical data center environments.
