全光网下光接入网的建设发展趋势探讨

Discussion on the Development Trend of Optical Access Network Under the Condition of All Optical Network

随着宽带中国战略的实施,用户宽带网络已实现全光化,有线接入网的发展将从解决最后一公里接入带宽瓶颈逐渐向优质化、精品化、智能化的综合化承载网络演进。Internet业务和多媒体应用的快速发展,网络的业务量正在以指数级的速度迅速膨胀,这就要求网络必须具有高比特率数据传输能力和大吞吐量的交叉能力。光纤通信技术出现以后,其近30THz的巨大潜在带宽容量给通信领域带来了蓬勃发展的机遇,特别是在提出信息高速公路以来,光技术开始渗透于整个通信网,光纤通信有向全光网推进的趋势。文中主要从光接入网的网络优化升级、应对无线5G光网资源储备以及智能ODN几个方面进行探讨。

With the implementation of the broadband strategy in China, the subscriber broadband network has become fully opticalized. The development of the cable access network will gradually evolve from solving the bottleneck of access bandwidth in the last kilometer to becoming a high-quality, refined and intelligent bearer network. With the rapid development of Internet services and multimedia applications, the network traffic is rapidly expanding exponentially. This requires that the network must have high bit-rate data transmission capability and high throughput cross-cutting capability. After the appearance of optical fiber communication technology, its huge potential bandwidth capacity of nearly 30 THz has brought a booming opportunity in the field of communication. Especially since the information superhighway was proposed, optical technology began to penetrate the entire communication network. Optical fiber communication has been provided to all optical networks Promote the trend. The paper mainly from the optical access network optimization and upgrading of the network to deal with the wireless 5G optical network resources reserve and intelligent ODN several aspects.
