FAQs

Q: Does this AOC support 4x100G or 8x50G breakout?
A: No. This is a straight 400G-to-400G QSFP-DD to QSFP-DD AOC and does not provide breakout.

Q: Do I need separate patch cords or patch panels?
A: No. The optical fibers are integrated in the AOC; simply plug each QSFP-DD end into 400G ports.

Q: Is it compatible with any QSFP-DD 400G Ethernet port?
A: It works in standards-compliant QSFP-DD 400G Ethernet ports that accept the corresponding module coding.

Q: What bend radius should I observe?
A: Follow standard best practices for active optical cables; avoid sharp bends and maintain gentle cable routing.
