We are looking to deploy a new data center build-out with Nexus 7ks and Nexus 2ks(FEX). I know the Nexus 2ks come bundled with the Fabric Extenders to be used to uplink to the Nexus 7ks. Our plan however is to put Gigamon fiber taps in-line of all of our uplinks back to our Nexus 7ks. Based off what I understand the FET needs to connect on one end to a FET on the other end. Would the SFP+ used on the in-line fiber taps cause a problem? Does anyone have experience with this? I'm considering just going with 10G SFP+ optics everywhere and not using the FETs.
