- Waterluvian 2y agoOhh there’s physical electronic repeaters. Okay. I thought this was some sort of electromagnetism witchcraft.
- bee_rider 2y agoIt’s all witchcraft anyway. I’m not sure what they use exactly, but even photodiodes are pure witchcraft.
- nbernard 2y agoThere is still some witchcraft. Look up "optical pumping amplifier" for instance.
- cyberax 2y agoThey actually are witchcraft. They amplify the signal directly, without transforming it into electrical signal.
