Introduction
光纤通信由于具有损耗低、传输频带宽容量大、体积小、重量轻、抗电磁干扰、不易串音等优点而备受业内人士的青睐,发展非常迅速。 Optical munications has developed rapidly because of low loss ,large transmission band of tolerance, small size, light weight, resistance to ic interference, crosstalk and other advantages .从SDH(同步数字系列)发展到DWDM(密集波分复用),超大容量密集波分复用技术的飞速发展使光纤的容量得到了比较彻底的发掘,解决了网络节点间传输容量的问题。 From the SDH (Synchronous Digital Hierarchy ) to the development of DWDM (Dense Wavelength Division Multiplexing), large-capacity dense wavelength division multiplexing technology which enable the rapid development of the capacity of optical fiber has been more thoroughly explore and work problems transmission capacity between 。 However, work node bottlenecks still very prominent.
随着各种光传送网技术的商用,各大运营商都在探讨光传送网技术的引入问题。 With mercialization of a variety of optical work technolog
