Research on Unrepeated and Ultra-long Span Transmission Technologies in Communication Network Based on SDH
The paper briefly introduces the limiting factors of ultra-long span and unrepeated for optical transmission system, Which are fiber of loss, dispersion, nonlinear. Introduces the current status of technology development in international. Then proposes some solutions .including Raman Fiber Amplifier and technology of FEC. Finally, it puts forward the scheme of 2.5G/bit unrepeated and ultralong span transmission based on SDH. The scheme adopts mature technique, uses devices easily available, therefore has high ratio of quality over price.
