Description

QSFP+ to 4x SFP+ active copper breakout cable that enables four discrete 10G links from a single 40G port over a compact 7 m assembly. Active equalization improves signal integrity over longer copper runs while maintaining ultra-low latency and simple plug-and-play deployment. Ideal for short- to mid-length top-of-rack fan-outs where the switch supports 4x10G breakout.

Features

- Four 10G links from a single 40G QSFP+ port
- 7 m active copper reach with low latency
- No separate optics or patch cords required
- Simple, secure latching for reliable installation
- Cost-effective fan-out for ToR and aggregation
- Standards-aligned CR4 breakout; verify platform support

Q: What switch configuration is needed?
A: Enable 4x10G breakout (fan-out) on the QSFP+ port if required by your platform.

Q: Is it compatible with any vendor device?
A: Compatibility depends on device acceptance of cable coding and breakout support. Check your platform matrix.

Q: What applications fit a 7 m length?
A: In-rack or adjacent-rack connections where copper is preferred and fiber is unnecessary.
