FAQs

Q: Is this module compatible with standard QSFP+ 40G ports?
A: Yes, it is designed for QSFP+ 40G ports on standards-compliant switches and routers; always verify platform interoperability for your specific device and firmware.

Q: What fiber and connectors are required?
A: Use OM3/OM4 multimode fiber with an MPO-12 (MTP) connector. For breakout, use an MPO-12 to 4x LC harness.

Q: Can I use this for 4x10G breakout connections?
A: Yes. It supports 1x40G to 4x10G breakout when the host platform enables breakout mode and you use an appropriate MPO to LC harness.
