１摇光以太网的概述现今网络的发展趋势是：光网络从广域网和城域网向本地网渗透；随着１０G以太网标准（IEEE８０２郾３ae）即将形成，以太网的分布得以从局域网延伸至城域网和广域网。光网络与以太网的融合和发展形成了光以太网，因此，光以太网集中了两者的优点，如以太网的
1 Overview of Lightning Ethernet The trend of today’s networks is that optical networks penetrate the WAN from MAN and MAN. As the 10G Ethernet standard (IEEE 802.3e) is about to be formed, the Ethernet distribution extends from the LAN MAN and WAN. Optical Ethernet and Ethernet convergence and development of the formation of optical Ethernet, Ethernet, therefore, focus on the advantages of both, such as Ethernet
