FAQs

Q: Will this work across different vendors’ NDR devices?
A: Use on systems that explicitly support twin‑port OSFP NDR ACC assemblies; cross‑vendor interoperability depends on device firmware and qualification lists.

Q: Is any wavelength involved?
A: No. It is a copper direct‑attach assembly; wavelength does not apply.

Q: Can it be routed in cable managers?
A: Yes, respect the minimum bend radius and avoid sharp bends or pinch points.
