FAQs

Q: Which fiber and connector does this module require?
A: Use OM3/OM4 multimode fiber with an MPO-12 (MTP-12) trunk and appropriate polarity/cassette.

Q: Is it interoperable with other vendors’ 100G SR4 optics?
A: Yes. It follows IEEE 802.3bm 100GBASE-SR4 and will interoperate with compliant SR4 modules over MMF with MPO-12.

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

Q: Can I break out to 4×25G?
A: Interoperability at 4×25G is at the optical level; breakout depends on the switch/patching architecture, not the module alone.
