基于SOA的长距离无源光网络理论与实验研究
|
摘要
无源光网络(PON)通过时分复用共享光纤和中心局的设备,每个用户的成本非常低廉,因此被认为是解决“最后一公里”的最理想的解决方案。随着带宽需求的快速增长,特别是网络技术P2P (peer-to-peer)出现后,光接入网中开始利用更多的复用技术,继续保持PON网络低成本的优势。在众多的复用技术中,波分复用无源光网络(WDM-PON)以其充分利用光纤巨大的带宽资源,迎合了带宽快速增长的趋势,获得了人们的广泛认同。但是目前高成本的WDM器件限制了其在接入网中的应用。波分时分混合复用PON(HPON)结合了时分复用的成本优势和波分复用的带宽优势,是由当前TDM-PON向WDM-PON过渡的理想解决方案。
通过扩展物理覆盖范围,长距离无源光网络(LR-PON)将光接入网和城域网整合进一个系统,简化了网络的结构,减少了设备之间的接口数目、网络设备以及节点数,从而网络的成本得到缩减。本论文在国家“十一五”“863”计划项目的基础上,围绕长距离波分时分混合复用无源光网络进行了深入的分析研究和技术创新。论文的主要内容如下：
(1)总结并分析了基于半导体光放大器交叉增益调制效应的全光波长转换器(AOWC)的工作原理和应用范围,并提出一种利用EDFA的增益特性来对AOWC的动态输入范围进行扩展的方法,从而实现了基于全光波长转换的长距离波分时分混合复用无源光网络的原理性样机。
(2)总结并分析了基于RSOA的无色ONU的工作原理和应用范围,对其动态输入范围、传输特性进行了理论和实验性的研究,分析了色散、后向瑞利散射、功率损耗等对其性能的影响。
(3)提出了一种基于AOWC的长距离波分时分混合复用无源光网络结构,并分别进行了2.5Gbit/s速率的实验研究和10Gbit/s速率的仿真研究,对长距离传输后的系统性能进行了测试和分析。为适应实际应用的需求我们提出了10Gbit/s速率的全光信号均衡器,并进行了理论分析和研究。
(4)提出了一种基于RSOA的长距离波分时分混合复用无源光网络结构,对长距离传输带来的色散控制、功率补偿等进行了研究,针对后向瑞利散射,提出本地光源的方式,来避免其对上行光信号的影响。
(5)提出了一种分布式接入方案,解决了长距离接入网中单点接入覆盖范围小,存在盲区的问题,实现了80km传输距离内的无盲区覆盖。并可以灵活增加接入点,以提高支持的用户数量以及增加系统的带宽。
Passive optical network (PON) is regarded as one of the most promising solution for the first mile, by sharing the feed fiber and central office equipments to a large number of subscribers. However, with the rapid growth of the bandwidth demands, especially after the appearance of the peer-to-peer (P2P) networking technology, many multiplexing techniques are deployed in the access network to maintain the cost-effectiveness of PONs. In all kinds of technologies, wavelength-division-multiplexed passive optical network (WDM-PON) has been regard as a promising solution to meet the fast increasing tendency. But the expensive WDM device cost limits its applications in the optical access network in which cost is shared by a few subscribers. Hybrid TDM/WDM PON (HPON) is a promising optical access network solution taking advantages of both TDM-PON and WDM-PON. HPON is suitable for near future deployment in pragmatic migration from current TDM-PONs to future WDM-PONs.
By providing extended coverage, LR-PON combines optical access and metro networks into an integrated system. Thus, cost savings are also achieved by simplifying the network, reducing the number of equipment interfaces, network elements and even nodes. The research in this dissertation was supported by the national "Eleventh Five-Year" " 863 " Program Project, launched a system-depth analysis and technical innovation on long reach WDM/TDM hybrid passive optical network. The main contents of this thesis are as the follo wings:
(1) Operation principle and operation conditions for all-optical wavelength conversion module based on the cross-gain modulation (XGM) effect of the semiconductor optical amplifier (SOA) are summarized and analyzed. An efficient extension method for the dynamic input range of the AOWC is proposed and a prototype system of long reach WDM/TDM hybrid passive optical network based on the AOWC is realized.
(2) Operation principle and operation conditions for the colorless optical network unit (ONU) based on the reflective SOA (RSOA) are summarized and analyzed. The dynamic input range of the colorless ONU and the performance of the system transmission are experimental studied. The effections of chromatic dispersion, Rayleigh Backscattering (RB) and power losses are also analyzed.
(3) An AOWC-based long reach WDM/TDM hybrid passive optical network is presented. An experimental system at 2.5Gbit/s and a simulation system are setup to help us to analyze the performance after the long reach transmission. An all-optical signal equalization module at 10Gbit/s is proposed for the practical applications.
(4) An RSOA-based long reach WDM/TDM hybrid passive optical network is presented. The chromatic dispersion control and the loss compensation introduced by the long reach fiber transmission are analyzed. For avoiding the effection of the RB, the local seed light source is suggested.
(5) A distributed access scheme is presented. Compared with the traditional long reach access schemes which usually have one access point, it can cover the area along the 80km feed fiber without blind zone. The access points can be flexibly inserted for supporting more users and providing more bandwidth.
