Transistors that can pass 120gbps are probably expensive as hell, possibly into InP territory.
The cheapest way to do this is over OS2 fiber. Look up how much money you have to spend to get 2x 100gbps OS2 PHYs and 2x 100gbps QSFP28 cards.

- wyager 4y agoInternal busses can operate in parallel, at some fraction of the serial bandwidth. You only need really fast stuff at the PHY. An interleaver/deinterleaver circuit is not much more complicated than the kind of signal shaping hardware you would need multiple copies of in the cable.
