2016: Half a Century of Optical Fibre Communications

2016 was the 50th anniversary of the publication that started it all.

Optical Fibre has transformed our world yet is now almost completely ignored.

The reasons?:

  • It is largely hidden (beneath our streets and oceans).
  • No surviving commercial organisation has an interest in promoting the STL history.
  • Few remember just how poor global communications used to be.
