FAQs

Q: Can I connect one 40G port to four 10G ports with this cable?
A: Yes. It provides a 1x40G to 4x10G breakout from a QSFP+ port to four SFP+ ports.

Q: Do the connected devices need to support breakout mode?
A: Yes. The QSFP+ host device must support 4x10G breakout for proper operation.

Q: Is the cable passive or active?
A: It is a passive twinax DAC, offering very low latency and no external power requirement.

Q: What standards does it follow?
A: It conforms to the QSFP+ and SFP+ MSAs and supports 40GBASE-CR4 breakout to 10GBASE-CR lanes.

Q: Typical use cases?
A: Fan-out from a 40G switch port to four 10G server NICs or 10G switch ports within the same rack.
