Multi-port RFC2544/EtherSAM loopback appliance

[Jason Lixfeld <jason () lixfeld ca>]

Group,

I'm looking for options and opinions on a cost effective, multi-port (6'ish port SFP/SFP+) RFC2544/EtherSAM rack 
appliance that can act as the remote/loopback for our field installers' portable RFC2544/EtherSAM enabled Exfo test 
sets.

I came across XenaNetworks XenaCompact which looks like it would fit the bill, but I'm sure there are others (save 
Ixia, Exfo and Fluke, which I'm pretty much excluding by default because I imagine they are likely completely out to 
lunch on price relative to the extremely simplified feature set we require).

Thanks in advance.
