FAQs

Q: Do I need separate SFP+ or QSFP+ modules?
A: No. The cable has integrated QSFP+ and SFP+ ends; just connect to compatible ports.

Q: What configuration is required?
A: Enable 4x10G breakout on the QSFP+ port if not automatic; naming varies by platform.

Q: How far can a 1 m passive DAC run?
A: 1 m is ideal for intra-rack links; passive DACs are generally used up to a few meters depending on gauge and host support.

Q: Is it interoperable across vendors?
A: It is MSA-based; ensure host ports accept the cable coding and support breakout.
