A: No. OSFP and QSFP-DD are different form factors and are not cross-compatible.

Q: Can this module be used for breakout?
A: Yes, SR8 can be used for 8x50G breakout with appropriate MPO-16 breakout cabling and platform support.

Q: What fiber and reach should I expect?
A: Up to 70m on OM3 and up to 100m on OM4, following 400GBASE-SR8 specifications.

Q: Does it require special polarity?
A: Use standard MPO-16 polarity and high-quality cleaning/inspection practices for parallel optics.

Q: Is digital diagnostics supported?
A: OSFP transceivers typically provide DOM/diagnostics; actual visibility depends on the host platform.
