FAQs

Q: Can I use this 7 m AOC to connect a 100G port to four access switches at 25G?
A: Yes, provided the 100G port supports 4×25G breakout and the 25G ports accept SFP28 AOC ends.

Q: Does this require separate fiber jumpers?
A: No. The AOC includes the fiber within the assembly; plug the QSFP28 and SFP28 ends directly into the ports.

Q: Is vendor coding required?
A: Many platforms require matching coding. Confirm your device’s transceiver compatibility list for AOC support.

Q: Is FEC needed for 7 m?
A: Typically not required at this short length, but follow your platform’s best practices for link robustness.

Q: Can it be field-terminated or cut to length?
A: No. AOCs are factory-terminated fixed-length assemblies.
