FAQs

Q: What transceivers and cables are supported?
A: Standard 40G QSFP+ modules (e.g., SR4/LR4 subject to switch/optic selection) and QSFP+ DAC/AOC cables are supported. Use modules/cables that match your switch and desired reach.

Q: Are optics included?
A: No. Transceivers and cables are sold separately unless explicitly bundled.

Q: Is it compatible with virtualization platforms?
A: Yes. SR-IOV and common offloads are supported when enabled by the appropriate driver on Linux, Windows Server, or VMware ESXi.

Q: Will this work in standard servers?
A: It fits servers with an available PCIe Gen3 x8 (or higher) slot. Always verify mechanical clearance and firmware/driver support with your server vendor.

Q: Does it support jumbo frames?
A: Yes, jumbo frames are supported (configure MTU end-to-end to match your network policy).
