FAQs

Q: What cable plant is recommended?
A: Use SMF with MPO-12 APC trunking; deploy MPO-12 to 4x LC duplex breakouts or cassettes as needed at the 100G side.

Q: Can this interoperate with 100G DR optics?
A: It is designed for 100GBASE-FR (2 km). Interoperability with DR (500 m) is not guaranteed; match standards on both ends.

Q: Is any special configuration needed?
A: Enable and configure 4x100G breakout mode on the QSFP-DD port according to your platform’s documentation.

Q: Is this suitable for long-haul links?
A: No. FR is specified for 2 km SMF. Use LR/LR4 or coherent optics for longer distances.
