I make my own open source FPGA switches, 6 and 12 port 10 Gbps SFP+ up to 100 Gbps QSFP28. Older model described in [1]. Email me if you want one. I also sell cheap $150 10 Gbps and 25 Gbps QSFP28 switches but they are only partially open source. They still sell some of the NetFPGA models, very pricy [2]. There are a few Chinese and Russian switches but you can't buy them anymore because of the war.
