FAQs

Q: Are SFP56 optics or DACs included? A: No. Use compatible 25G/50G SFP56 DAC/AOC/optical modules.

Q: Can ports run mixed speeds (25G and 50G)? A: Yes, ports can be configured per‑port within supported profiles.

Q: Does it support telecom timing profiles? A: It supports PTP and Enhanced SyncE; consult release notes for specific profiles and options.

Q: Is PCIe generation fixed? A: The adapter uses a x16 interface and is compatible with modern server PCIe generations; bandwidth scales with the host slot.
