Kao was already in Alzheimer’s condition when he received the Nobel prize, I remembered in an interview after the prize was announced, he could barely recall what optical fibre is. May he rest in peace and forever remembered번역 보기

I worked in telecom for 43 years, I retired a little over a year ago. I remember going from analog to digital electrical cables, and then to digital fibre transmission. The bandwidth of fibre has yet to hit its limit. The limit is actually the switching speed of the electronics on either end of the fibre. They now use lasers of different "colours" or Lamdas, with prisms to separate the multiple beams that travel down a single fibre. The technology is amazing.번역 보기
