Cisco Platform Compatibility:

The FET-10G is officially supported on Cisco Nexus Fabric Extender (FEX) uplinks:

• Nexus 2000 Series Fabric Extenders (2232, 2248, 2348) → parent switch uplinks
• Parent switches: Nexus 5000, 5500, 5600, 7000, 9000 Series

Also commonly used as a standard 10GbE SR SFP+ in other Cisco platforms (Catalyst 3850/9300/9500, Nexus 3000/9000 standalone) — may require service unsupported-transceiver command on some platforms.

Important — Cisco Only:

This is a Cisco-coded transceiver. It will NOT work in non-Cisco equipment (Arista, Dell, HPE, Juniper, Intel NICs). These platforms will reject the Cisco vendor EEPROM coding. If you need a 10G SR SFP+ that works across multiple vendors, look for a generic/MSA-coded module like the Finisar FTLX8571D3BCL instead.
