FAQs

Q: Is 15 m suitable for row-to-row breakout in a data hall?
A: Yes. 15 m is commonly used for row-to-row or end-of-row fan-out when ports support 4×25G breakout.

Q: Will it interoperate across different vendors’ switches and NICs?
A: The AOC is MSA-based but may still require appropriate vendor coding. Verify compatibility with each endpoint.

Q: Does the cable support monitoring?
A: Yes. DDM/DOM telemetry is supported for link health and diagnostics.

Q: What happens if a single 25G leg is down?
A: Each 25G lane is independent; investigate that lane’s endpoint/port while others typically remain unaffected.

Q: Is this cable field-repairable?
A: No. It is a factory-terminated fixed assembly; replace if damaged.
