FAQs

Q: How does an AOC differ from a DAC?
A: AOCs use optical fiber with integrated transceivers for longer reach, lower EMI, and flexible routing; DACs use copper twinax for short, ultra-low-latency links.

Q: Do I need separate optical transceivers?
A: No. The optical transmitter/receiver are integrated into the SFP28 ends.

Q: Is it hot-pluggable?
A: Yes, the SFP28 ends are hot-pluggable.

Q: Can it be field-terminated or reworked?
A: No, the AOC is factory-terminated at a fixed length.

Q: Is it compatible with any SFP28 25G port?
A: It is designed for SFP28 25G ports; ensure device compatibility with SFP28 AOC cables.
