FAQs

Q: What does Type B polarity mean for this cable?
A: Type B polarity reverses the fibre positions end to end, so fibre 1 at one connector lands on fibre 12 at the other. This is the polarity commonly used for parallel optic links such as 40G and 100G SR4.

Q: Is this cable suitable for 40G and 100G SR4 optics?
A: Yes. It is an MPO-12 multimode trunk designed for 850 nm 40G and 100G SR4 links over short reach.

Q: What connectors does this cable use?
A: It has MPO-12 connectors on both ends, so it connects directly to MPO-12 optics, cassettes or panels.

Q: Can this cable be used for single-mode links?
A: No. This is a multimode (MMF) cable intended for 850 nm short-reach links, and it should not be used for single-mode optics.
