摘要
在光传输系统中优化设计,利用放大、前向纠错、色散补偿等技术,可大大增加无中继超长站距传输距离。文章采用最坏计算法,利用不同放大技术组合对无中继超长站距传输距离进行计算。设计与计算结果显示均满足无中继超长站距传输条件。
In optical transmission system, optimized design, amplification, FEC and dispersion compensation technologies can greatly increase non-repeater transmitting span. This paper uses the worst method to calculate non-repeater ultra-long span via different amplification technologies. Calculation results on some optical fiber practical applications show that they all satisfy requirements of non-repeater ultra-long span transmission.
