摘要
光时分复用(OTDM)与密集波分复用(DWDM)传输技术是增加光通信系统容量的两个主要途径,可以充分利用各自的优点,构筑未来高速、大容量光通信网络。论文结合国家自然科学基金重点项目“高速光通信系统中的偏振模色散补偿及其相关技术与基础研究”(No.60437010)和国家863计划项目“160Gbit/s一泵多纤光传输技术的研究”(No.2007AA012258)的实施,针对高速OTDM系统的关键技术:新型调制码型、160Gbit/s OTDM所需的超短脉冲源及光时分复用器、单信道160Gbit/s传输的色散和带内非线性效应、接收端的解复用和时钟恢复等进行了深入分析和探讨,主要创新性研究工作体现在:
     (1)采用应力调节装置制作了性能稳定的窄带光纤布拉格光栅(NFBG),利用NFBG获得了10Gbit/s的残留边带归零调制码型(VSB-RZ)。通过在实验室的WDM光路交换实验网平台上进行了10Gbit/s的RZ与VSB-RZ在155km单模光纤(SMF)上的传输,验证了所获得的VSB-RZ码型的可行性。
     (2)建立了基于低速率超短脉冲源复用产生高速率OTDM信号的理论模型,基于此模型分析了10GHz脉冲源的消光比、光信噪比及光时分复用器的非理想性对160Gbit/s OTDM信号性能的影响。对OTDM传输系统的优化和改进具有理论指导作用。
     (3)理论分析了光纤色散、带内四波混频和带内交叉相位调制对单信道160Gbit/s信号传输性能的影响。并给出色散及色散斜率补偿的方式及对应的实验结果。
     (4)提出了两种可以同时完成对160Gbit/s OTDM信号进行时钟提取及解复用为10Gbit/s信号的方案:a.采用两个电吸收调制器(EAM)级联和10Gbit/s的时钟数据恢复单元(CDRU)形成的反馈环路;b.采用EAM、40Gbit/s的电时分解复用器和时钟恢复模块形成的反馈环路。实验证明两种方案结构简单、经济,能提取出稳定的时钟信号。
     (5)建立了160Gbit/s OTDM信号传输100km的实验系统,误码率为10-9量级时的功率代价为3.5dB。在此基础上进一步完成了2×80Gbit/s和2×160Gbit/s光偏振/时分复用信号的传输实验,误码率为10-6量级时的功率代价分别为0.6dB和1.5dB。
Optical time-division multiplexing (OTDM) and dense wavelength dividion multiplexing (DWDM) are two main technologies of increasing capacity of optical communication system. They can be used to achieve next generation high-speed and large-capicity optical communication networks. This dissertation is supported by the key projects of National Natural Science Fondation "Research on polarization mode dispersion (PMD) compensation and related infrastructure technologies in high speed optical communication systems " and National High-Tech Research and Development Program of China "Study on key technologies in 160Gbit/s OTDM transmission system using multi-fiber pump". In this dissertation, key technologies in OTDM system are investigated, i.e. novel optical modulation formats, ultra-short pulse source, optical time division multiplexer, dispersion, intra-channel nonlinear effects, clock recovery and demultiplexing. The main innovative achievements are listed as follows:
     (1) Robust narrow fiber bragg grating (NFBG) is fabricated by a kind of stress-tuable equipment, and lOGbit/s vestigial sideband return-zero (VSB-RZ) is obtained. The transmission of and RZ over 155km signal mode fiber (SMF) is accomplished in all-optical experimental WDM network. The results show that the VSB-RZ is feasible.
     (2) A theoretical model of OTDM based on low repetition rate pulse source is established. The influence of extinction ratio, optical signal to noise ratio of 10GHz pulse source and non-ideal performance of optial time division multiplexer on the 160Gbit/s OTDM signal is analyzed. This is helpful for the optimization and elevation of OTDM tramsimssion system.
     (3) The effects of dipersion, intra-channel cross phase modulation (IXPM) and intra-channel four-wave mixing (IFWM) on transmission performace of single 160Gbit/s signal are analyzed. The experiment of dispersion and dispersion slope compensation is accomplished.
     (4) Two methods for simultaneous demultiplexing and clock recovery are proposed:(a) demultiplexing and recovery feed-back loop formed by two tandem EAMs and lOGbit/s clock data recovery unit (CDRU); (b) demultiplexing and recovery feed-back loop formed by EAM,40 Gbit/s electrical time division demultiplexer and clock recovery model. Experimental results prove that these two methods can recover the clock signal successfully and the structures are simple and economic.
     (5) The experimental transmission system of 160Gbit/s OTDM over 100km is established, the power penalty is 3.5 dB when bit error rate is 10-9. The transmission experiments of 2×80Gbit/s and 2×160Gbit/s optical polarization/time division multiplexing are accomplished, the power penalty are 0.6 dB and 1.5dB when bit error rate is 10-6, respectively.
