FAQs

Q: What fiber type and connector do I need?
A: OM3/OM4 multimode fiber with an MTP/MPO-24 trunk. Each 100G SR4 leg uses 8 fibers and is carried within the single MPO-24 interface.

Q: What is the maximum reach?
A: Up to 100 m on OM4 and up to 70 m on OM3 per 100G leg.

Q: Does my device need to support breakout?
A: Yes. Enable 2x100G breakout on the QSFP-DD port.

Q: Can each leg link to a standard 100G SR4 transceiver?
A: Yes. Each breakout channel interoperates with a standard 100GBASE-SR4 optic.

Q: Is DOM supported?
A: Yes, digital diagnostics are available for monitoring.
