FAQs

Q: Is an MPO trunk cable included?
A: No. Use an MPO-12 multimode trunk (Type-B polarity) rated for OM3 or OM4.

Q: Do I need OM4 fiber for full distance?
A: OM3 supports up to 100 m; OM4 is recommended to achieve up to 150 m.

Q: Is the connector pinned or unpinned?
A: The module presents an MPO-12 female (unpinned) interface; the cable should have male pins.

Q: Can this interoperate with other vendors’ SR4 optics?
A: Yes, it is MSA and IEEE compliant; cross-vendor SR4 links are supported when fiber and polarity match.
