FAQs

Q: Is this module compatible with duplex LC single‑mode patch cords?
A: Yes, it uses a duplex LC connector and is designed for G.652 SMF.

Q: Does it require forward error correction (FEC)?
A: Operation is host-dependent; RS-FEC is recommended by most platforms for optimal BER.

Q: Can this be used for breakout (4x25G)?
A: No, 100GBASE-LR4 is for 100G point‑to‑point links, not 4x25G breakouts.

Q: Does it support DOM/DDM?
A: Yes, digital diagnostics monitoring is supported.
