FAQs

Q: What does Type B polarity mean?
A: Type B (key up to key up) preserves fiber order for parallel optics like SR4/PSM4, enabling end‑to‑end straight‑through mapping.

Q: Is this cable compatible with QSFP SR4 modules?
A: Yes, if your transceiver uses an MPO‑12 multimode interface. Ensure the installed multimode grade and link budget meet your distance needs.

Q: Is the connector pinned (male) or unpinned (female)?
A: Pinning is not specified. Check your hardware requirements and confirm the pin type needed for your MPO ports or cassettes.

Q: Can I use this for InfiniBand links?
A: Yes, it supports multimode MPO‑12 connections used by many InfiniBand and Ethernet parallel‑optics implementations. Verify polarity and pin type compatibility.
