Worth mentioning that this is from 2021 and there are now faster speeds and more options.

We have OSFP/QSFPDD with 8 lanes and lane speeds of 100Gpbs and 200Gbps for up to 1.6Tbps on a single DAC at the bleeding edge. Although with these signal integrity limits the maximum length to about 1m.

You probably won't see this on a NIC or anything for home use any time soon though.
