【摘要】 光传送网是网络技术发展的重要基础。波分复用技术对充分利用光纤的巨大带宽提供了一个可行的解决方法,并且正迅速变成未来电信网络的传送基础设施结构。这种技术的一个吸引人的方面是能既经济而又迅速地在单根光纤中增加传送容量。当前,研究人员正在发展能提供256甚至于更多波长通道的波分复用系统,提供多个太比特的容量。讨论了新一代光网络ASON以及它的三个平面,并对每一个平面的功能进行了研究,最后对ASON技术的发展进行了分析。更多还原

【Abstract】 Optical transport network is an important foundation of network technology development.Wavelength division multiplexing(WDM) technology offers a viable solution to fully exploit the enormous bandwidth available in fiber optics and is rapidly becoming the dominant transport infrastructure for future telecommunication networks.An attractive feature of this technology is its ability to economically and rapidly increase the transmission capacity of a single optical fiber.Currently,researchers are developing WDM systems with 256 and higher wavelengths channels offering multi-Tera-bit /s capacity.Its new generation optical network ASON and three planes are discussed in this paper.Every plane function is researched,and finally the development of ASON technology is analyzed.更多还原
