I can't imagine that subtle light intensity would survive the various light amplifiers used along the way.

  Analog signals won't survive a 1000km undersea cable, but for a few kilometers you don't need amplifiers at all. The loss-per-meter of optical fiber is much lower than a coax cable.

  This is exactly how hybrid fiber-coax works for CATV.
