Description

Direct-attach copper breakout cable enabling one 40GbE QSFP+ port to split into four 10GbE SFP+ links. Ideal for TOR switch-to-server connections that need up to 3m reach while maintaining low latency and low power. Supports 40GBASE-CR4 on the QSFP+ side and 10GBASE-CR on each SFP+ lane.

Features

- Breaks out a single 40GbE QSFP+ port to four 10GbE SFP+ links
- 3m reach balances flexibility with tidy cable management

FAQs

Q: Do I need special configuration for breakout?
A: Many switches require enabling 4x10G split mode on the QSFP+ port. Follow your platform’s configuration guide.

Q: Is 3m suitable for in-rack cabling?
A: Yes. 3m accommodates most TOR to server paths and adjacent rack runs.

Q: Can this be used across different vendor devices?
A: It may work, but vendor coding can affect compatibility. Verify support on both ends.

Q: Does this replace separate optical transceivers?
A: Yes. It is an integrated copper solution requiring no additional optics.

Q: What’s the benefit over optical breakout?
A: Lower cost and power for short reaches; optical is preferred for longer distances.
