I’m not the op, but I can recommend the Unifi link aggregation switch and cheap Mellanox connectX3 cards. They are about $20 and are amazing. Fibre runs aren’t expensive but the transceivers are so copper DAC is good for short runs (as the connectors are built in).

Thunderbolt sfp adaptors also work.

You can thank early HFT and other early customers for those juicy cheap Mellanox cards. They used to be thousands when they first came out.

Fibre transceivers are not expensive. You can get 2km 1310nm single mode 10G SFP+ modules for US$15 here: https://www.fibermall.com/sale-420055-sfp-10g-ir-1310nm-2km....
