FAQs

Q: Is 20 m suitable for 100G PSM4 runs?
A: Yes. OS2 single‑mode easily supports 20 m for parallel SMF applications when polarity and connector pinning match.

Q: What polarity plan does this use?
A: Type-B, which is key-up to key-up for straight-through fiber mapping used by many MPO-12 parallel optics.

Q: Can it be used with MPO cassettes?
A: Yes, as long as the cassettes and overall channel maintain the required Type-B polarity and pinning.

Q: Is it MTP compatible?
A: Yes. It is compatible with MTP/MPO interfaces under matching polarity and gender.

Q: Is the jacket low-smoke, halogen-free?
A: Yes, LSZH jacket.
