Cisco Nexus 93180 Pseudowire config for traffic test

I have a nexus 93180 that I need to run a traffic test on. Connecting a Tberd traffic tester to an SFP in port 1. In port 3 and 4 are two identical optics connected to each other. Ports 5&6 have another set of two identical optics connected together. 7&8 same thing. Port 10 will be 1 last optic on a loop. All of the optics interfaces show up and functional. What I need to be able to do is pass traffic through all of the ports to port 10, then back. The recommendation to accomplish this was to create a pseudowire between the optical pairs and pass traffic to the last port. I attached a graphic given to me as an example. Can anyone provide a  sample config of how to set this up?User generated image

I might well be missing something here, but a "chain" is quite simple to do at L2, have port 1 &2 in VLAN1, 3&4 in VLAN2 etc. A "chain" might be used if one wanted to calculate latency by havign each end of the chain connected to the tester.

I'm not sure that the loopback will have the desired effect, the 93180 is an Ethernet switch, not an optical switch
