FAQs

Q: Is this module interoperable with other vendors’ 40G LR4 optics?
A: Yes. It follows 40GBASE-LR4 (IEEE 802.3ba). Interoperability requires standards compliance and, in some platforms, matching vendor coding.

Q: What fiber and connector do I need?
A: Use OS2 single-mode fiber with a duplex LC patch lead.

Q: Can this be used for 4x10G breakout?
A: No. LR4 over LC is not intended for 4x10G breakout; use 40G PLR4/MPO optics for breakout scenarios.

Q: Does it support digital diagnostics (DOM)?
A: Yes, DOM/DDM is supported for monitoring optical power, temperature, and voltage.
