FAQs

Q: Is host FEC required?
A: Yes. LRL4 implementations require RS-FEC on the host to meet the specified BER and reach.

Q: What fiber type should I use?
A: Use OS2 single-mode fiber terminated with duplex LC connectors.

Q: Will it interoperate with other vendors’ LRL4 optics?
A: Yes, when both ends are coded for the host platforms and support LRL4 with RS-FEC enabled.

Q: Is this suitable for breakout to 4x25G?
A: No. Use PSM4/MPO optics for 4x25G breakout scenarios.
