摘 要
随着信息化建设的快速发展,作为光电介质转换的关键设备,光纤收发器越来越受到人们的重视,同时人们对光纤收发器的要求越来越高,具体表现在智能化、稳定行和网管控制等方面。智能化方面,要支持链路状态故障转移、流量控制、端口自协商等功能。稳定性方面,光纤收发器应能更好地适应实际的网络环境。网管控制方面,要求管理者能够很容易的监控本地和远端光纤收发器,能够降低网络维护的成本。本文通过对国内外光纤收发器的分析和研究,设计出一种智能光纤收发器系统。
所设计的智能光纤收发器系统主要包括客户端、网络管理单元、光电转换单元和电源电路四部分。系统采用ARM7TDMI-S微控制器LPC2210为硬件核心,μCLinux操作系统为软件平台。通过对光纤收发器的功能以及工作原理研究,硬件设计了以ARM处理器(LPC2210)为核心的网络管理单元;以IP113S光电介质转换芯片为核心的光电转换单元;以及系统电源电路。
整个系统是基于B/S和C/S架构设计的,B/S架构是客户端可以是任何一台连入因特网的PC机,并且不需要安装任何专用的软件就可以查看智能光纤收发器系统的监控画面。C/S架构则需要在客户端安装相关网络管理软件(SNMPc V6)以及基于MiniGUI的液晶显示。系统的进行了μCLinux操作系统的移植;内嵌Web服务器;移植CMU-SUNP(Camegie Mellon University-Simple Network Management protocol)数据包;驱动程序与应用程序的开发。本设计从硬件和软件上均遵循了低功耗的设计思想。
对设计出来的整个系统进行测试,能实现对光电转换单元进行参数的自动检测、控制调节功能,整个系统运行稳定,达到了预期的目标。并开展了智能收发器系统实验研究。论文所研制的智能光纤收发器系统,在实验中取得了较好的效果,可以用于实际运行中,为下一代光纤收发器系统奠定了基础。

Abstract
With the rapid development of information technology, as a key equipment for optical media conversion, Fiber optical transceivers attracts more and more people’s attention, at the same time, people’s demand for fiber optical transceivers become increasing too. Embodied in intelligent, stable and network management and so on. Intelligent, it should support link fault pass-through, flow-control, port auto-negotiation function and so on. Stability, the fiber optical transceiver should be able to better adapt to the actual network environment. Network management, requires management to easily monitor local and remote fiber optical transceivers, reduce network maintenanace costs. Based on the analysis and research of domestic and international fiber optical transceivers, designed an intelligent optical transceiver systems.
The intelligent fiber optical transceivers system designed includes client, network management unit, photoelectric conversion unit, the system power supply circuit diagram four parts. The system uses ARM7TDMI-S microcontroller LPC2210 as the core of hardware, and the μCLinux operating system as the platform of software. Through the studying of fiber optical transceiver functions and working principle. It takes the ARM processor (LPC2210) as the core of network management unit and the IP113S optical media converter chip as the core of photoelectric conversion unit. And power circuit diagram of the system.
The whole system is based on B/S and C/S structure, B/S structure is that the client computer can be any PC which is connected to the Internet, and you can view the monitor picture of the intelligent fiber optical transceivers system, not needing to install any special software. C/S structure is that the client computer need to install related network management software (SNMPc V6) and LCD interface based on MiniGUI. The design has completed the transplanting of µCLinux operating system; the embedding of Web server; the transplanting of CMU-SNMP (Camegie Mellon University-Simple Network Management protocol) packet; the developing of driver and application program. This design follows to the idea of low power from hardware and software.
We have tested the whole system after it was designed. The system can achieve the function of detecting and regulating the photoelectric conversion unit. The system works stable, and it reaches the desired goal. Experiments based on the intelligent fiber optical transceivers system have been done.
The intelligent fiber optical transceiver system has achieved good results in the experiment, It can be used in the actual operation, and it lays the foundation for the next generation of fiber optical transceiver system
