【Abstract】 A new technical achievement——the multifunctional GC-J1 type optical fiber transmission system, the design principles, fabrications, investigation results and analysis discussions of it has been reported. It is the communication system which Color pictures and audio signals are transmitted simultaneously in the same fiber cable with single core. The signal-to-noise ratio S/N≥50 dB. By use of this system, it shows that the performances behave good stability and reliability. The optical modulation characteristics, differential gain (DG), differential phase (DP) and signal-to-noise ratio (S/N) are described as well in this paper.更多还原
