I am looking at building a network with Nexus 5000 parent switches and Nexus 2000 fabric extenders.
The mystery at the moment is what kind of SFP+ tranceivers are required for cross-connecting racks.
Right now I am considering FET-10G, but I am not sure that 100m is long enough given the separation between racks is potentially very large since it is a rented rack environment.
Are all SFP+ tranceivers usable for FEX between Nexus 5000 and Nexus 2000?
Specifically, can SFP-10G-SR transceivers be used for longer distance FEX?
