I understood perhaps mistakenly the OP's comment to mean each "repeater" point was an L2 hop.
But my main point was that the undersea spans are not in fact "repeatered" and there is no conversion of signal once it leaves land.
- hueving 9y agoYes, you are mistaken. "only one hop" was actually intended to mean only one hop.
- bogomipz 9y agoWell there's no such things as a "hop" at Layer 2. And as others also pointed out its an optical amplifier, there is no "decoded, error corrected, and re-transmitted" being done along the path of the submarine cable.
- hueving 9y ago>Well there's no such things as a "hop" at Layer 2. Only if you're being obtuse and don't actually work in networking. A hop in L2 is a device that does L2 forwarding and participates in L2 protocols like STP. >And as others also pointed out its an optical amplifier, there is no "decoded, error corrected, and re-transmitted" being done along the path of the submarine cable. This is only true for newer stuff. Look up OEO fiber repeaters. Those cables are still in use.
