FAQs

Q: Can I connect this directly to four 100G FR ports with LC?
A: Yes, via an MPO-12 APC trunk and MPO-12 to 4x LC duplex breakout harness or cassette to reach four LC-based 100G FR optics.

Q: Is fiber polarity important?
A: Yes. Use MPO-12 APC components with the correct polarity per your structured cabling design.

Q: Do I need platform support for breakout?
A: Yes. The QSFP-DD host must support 4x100G breakout mode.

Q: What applications is FR best suited for?
A: Campus and data center interconnects up to 2 km per lane where single-mode infrastructure is available.
