A structure of 10 Gbit/s fiber-optic transmission system was established to achieve 10 G optical signal transmission without relay and bit error. This system consists of NRZ format
GaInAsP multiple-quantum-well DFB lasers and LiNbO
3
electro-optic modulator.The transmission experiment was carried out to abtain the parameters of the system. The effect on transmission quality were also analyzed and some key questions were studied. Experimental results show that the transmission distance without relay is about 84 km. Using CWDM technology for multiplex signal
the sensitivity of receiver is about -26.76 dBm at BER= 10
-12
and the power penalty is about 0.49 dB without BER floor in the system. In the experiment
the relationship between extinction ratio and optical receiver sensitivity was also investigated
and the system runs continuously for 24 hours without error.
