| Abstract: | This article briefly introduces the four limiting factors of ultra-long repeating distance for 2.5 Gbit/s optical transmission system,which are attenuation,dispersion,signal-noise ratio and nonlinear effect.It advances the corresponding solutions such as erbium-doped fiber amplifier,distributed Raman amplifier,remote optical pump amplifier,forward correction as well as dispersion compensation,and proposes the performance parameters for each solution.The technical combination for different repeating distance and the maximum repeating distance for 2.5 Gbit/s optical transmission system are also given in the paper. |
