Technical Specifications

FAQs

Q: Is this cable passive or active?
A: Passive DAC.

Q: Can this be used for switch stacking or ISL?
A: Yes, if the switch platform supports 40G DAC for stacking/ISL.

Q: Does this support 4x10G breakout?
A: No. This is a straight 40G QSFP+ to QSFP+ cable, not a breakout.

Q: What is the recommended bend radius?
A: As a guideline, ≥10x cable diameter to avoid performance degradation.

Q: Will it work across different vendor QSFP+ ports?
A: DAC EEPROM coding and support can be vendor‑specific. Check your device’s compatibility matrix.
