Yes, you are mistaken. "only one hop" was actually intended to mean only one hop.

  Well 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.

    >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.
