摘要
对超长距离10Gb/s SDH光传输系统进行了实验。系统采用超低损光纤作为传输介质,使用增强型前向纠错(EFEC)技术、分布式宽谱泵浦技术和旁路遥泵技术。通过理论研究和实验测试,实现了单波10Gb/s同步数字体系(SDH)系统442.2km无中继传输。
The article introduces an experiment about ultra-long distance transmission of 10Gb/s SDH. Through the theoretical research and experimental testing, the transmission system has realized 442.2km unre- peated transmission for single wavelength of 10Gb/s SDH using ultra low loss fiber, enhanced forward error correction （EFEC）, distributed wide spectra pump amplifier and remote optical pump amplifier in additional fiber.
