Assuming you could produce viable consumer cables that are superconductors, my understanding is that there would be no signal loss, so your hypothetical cable could have infinite length.
Digital is digital so this would be true for any data use case.
Maybe someone smarter can chime in about how electromagnetic interference affects or doesn’t affect a hypothetical “superconductor cable.”
- mycall 3y agoThe longer the cable, the longer duration loopback signals take. This can affect timing of any synchronous specification. If it is too long, it could be out of scope of the spec and thus stop working. Maybe you can solve this with a transceiver MITM device.
- Waterluvian 3y agoOh right I forgot about that! So yeah… probably longer than you’d need but not infinitely long. Unless the protocol is fine with it.
- Filligree 3y agoSuperconductors only have zero resistance when measured in DC. AC still faces impedance, high frequency AC like DisplayPort especially so.
