Cisco’s specification states that the FET-10G is supported for fabric links only, and that one FET-10G must connect to another FET-10G. It is supported on compatible Cisco Nexus 2000 platforms and Cisco Nexus parent-switch fabric links, with platform support varying by Nexus generation.
Compatibility
The FET-10G serves Cisco’s Fabric Extender architecture rather than ordinary switch-to-switch optical connections.
Cisco documentation lists FET-10G support for compatible Nexus 2000 Series Fabric Extenders and fabric links involving Nexus 5000, 6000 and 7000 Series platforms; newer Nexus 2300 documentation also lists supported Nexus platforms. Always verify the exact Nexus model and software version before listing compatibility as guaranteed.
