Description

High-performance direct-attach copper breakout cable that fan-outs one 40GbE QSFP+ port into four 10GbE SFP+ links over low-latency twinax. Ideal for top-of-rack switch to server NIC connections and short intra-rack runs where simplicity, low power, and cost efficiency matter. Supports 40GBASE-CR4 on the QSFP+ side and 10GBASE-CR on each SFP+ lane across a 1m reach.

Features

- Converts one 40GbE QSFP+ port into four independent 10GbE SFP+ links
- Low latency, low power twinax copper for short-reach connections
- 1m length optimized for clean, clutter-free intra-rack cabling
- No separate optics needed—cost-effective and simple deployment
- Standards-aligned with 40GBASE-CR4 and 10GBASE-CR operation

Technical Specifications

FAQs

Q: Does this cable require separate transceivers?
A: No. The QSFP+ and SFP+ ends are integrated—no additional optics are required.

Q: Will this work on any 40G port?
A: The host QSFP+ port must support 4x10G breakout (split) mode. Check your switch or router documentation.

Q: Can I mix vendors across the cable ends?
A: DAC cables are often vendor-coded. For best results, use with devices that support the coding on both ends.

Q: What’s the typical application?
A: Connecting a 40G QSFP+ switch port to four 10G SFP+ server NIC ports within the same rack.

Q: Is this suitable for stacking ports?
A: Some platforms support stacking over DAC; confirm with your device feature guide.
