A: No. It is designed for multimode fiber (OM3/OM4).

Q: What connector type is required?
A: LC duplex connectors are required.

Q: Is it interoperable with 100G SR4 MPO modules?
A: No. It should be matched with another 100G SR1.2‑type module on the far end.

Q: Do I need FEC to achieve full reach?
A: Yes, KP4 FEC on the host is recommended to achieve the published reach.

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