FAQs

Q: What fiber and connector are required?
A: Use OS2 single-mode fiber with a duplex LC connector for 10 km LR4 links.

Q: Does this module require FEC?
A: LR4 does not mandate FEC; however, enabling host FEC can improve link robustness.

Q: Is DOM/diagnostics supported?
A: Yes, digital diagnostics (DDM/DOM) are supported for real-time monitoring.

Q: Can this be used for 4x25G breakout?
A: No. LR4 is designed for 100G duplex SMF. For breakout, use PSM4/MPO-based optics.
