摘要
光网络技术的迅速发展为因特网日益膨胀的信息流量提供了强大的传输支持。更为重要的是,光放大器和波分复用(WDM)技术的出现,不仅强化了光在网络中的地位,而且将其作用逐步扩大到网络边缘。随着光纤价格的逐渐下降以及企业与家庭用户对带宽需求的持续增长,光纤系统将逐步从核心网和城域网向接入网和企业局域网领域发展并显示出强大的生命力。可以预见,光将出现在所有的地方!
With the explosion of capacity demands driven by the Internet optical networking systems are experiencing tremendous growth and are providing increasingly high transmission capacities. As importantly with the advent of the optical amplifier and WDM optics is playing a larger role in networking and is extending further to the edge of the network. In addition as the cost of optics is driven down and the demand for bandwidth to businesses and residential customers continues to grow optical systems are extending out from the network core and metro to access applications. The confluence of a proliferation of broadband service applications and rapidly maturing optical technology are literally driving optical systems into all segments. Increasingly optics is literally everywhere.
