Q1: What does QSFP+ to 4x SFP+ breakout mean?
A: It means one 40G QSFP+ port is split into four independent 10G SFP+ connections for flexible network design.

Q2: What is a passive DAC cable?
A: A passive DAC (Direct Attach Copper) cable does not require external power and relies on copper conductors for short-distance transmission.

Q3: What is 40G-CR4?
A: 40G-CR4 is a standard for 40 Gigabit Ethernet using four parallel 10G lanes over copper cables.

Q4: What is the advantage of 30AWG cable?
A: 30AWG offers better flexibility and is suitable for tighter cable routing in high-density racks.

Q5: What is the maximum recommended usage distance?
A: This 3m passive DAC is optimized for short-reach connections within or between adjacent racks.
