FAQs

Q: Will this work with NDR-capable fabric switches and adapters?
A: Yes, provided the OSFP ports support 800G→4×200G breakout.

Q: Do I need transceivers?
A: No—this is an integrated active copper OSFP cable assembly.

Q: What distance does this model support?
A: 5 meters.

Q: Is it compatible with QSFP modules?
A: No. All ends are OSFP and must connect to OSFP ports.

Q: Why choose ACC over AOC here?
A: ACC offers the lowest latency and cost for short distances; AOC is preferred for longer runs.
