521 km超长站距无中继光传输系统研究

This paper introduces a 521 km ultra-long span repeaterless transmission in a 2.5 Gbit/s optical transmission system by utilizing Corning SMF-28 ULL ultra-low loss optical fiber as the transmission medium and such technologies as phase chirp, forward Raman, enhanced FEC and channel associated Remote Optical Pre-pumping Amplifier (ROPA). This is the longest transmission distance by using the ROPA technology reported so far.
