In today's society information development is rapid, optical fiber communication plays an irreplaceable role. Using optical fiber transmission medium as light of optical fiber communication has only twenty or thirty years, but the optical fiber communication research develops scope and rapid in the world, in short twenty years, from 0.85 um short-wavelength multimode fiber change to 1.31 um-1.55 um long wavelengths single-mode optical fiber, at the same time, develop many new photoelectric device, laser device life has reached 100,000 hours, or even millions hours, many countries have built more developed long fiber communication system. This paper mainly introduces the analog video by optical transmission, the first chapter introduces the background of the optical fiber communication; The second chapter inroduces optical fiber communication technology; The third chapter introduces the design and the targets of the video communication by fiber optical; The forth chapter introduces the imoportant technology as photo/electricity conversion and electricity/photo conversition; The fifth chapter introduces the experiment of the video communication. Finally I submit all.
