- rdl 14y agoYou can do repeater less fiber for longer and longer distances no, though -- probably around 1000km.
- MichaelSalib 14y agoThe really cool thing about the repeaters is that they're optical. They don't work by converting the incoming signal into an electrical impulse at all; instead, they amplify entirely in the optical domain.
- tibbon 14y agoCan you provide any more info as to how that works?

- delinka 14y agoErgo, the cables are not strictly only fiber optic. There are metal power lines as well.
