毕业设计（论文）-自适应10100M光纤收发器设计.doc

摘要
自70年代以来,光纤凭借自身的一些固有特性(如不受噪声干扰、保密性好以及高传输带宽等)成为各种应用领域的理想传输介质。近年来,随着布线标准的改变,光电器件、光缆、连接器技术的发展以及应用带宽的逐步升级,光纤网络产品应用日益普及,很多用户开始考虑用“光纤到桌面”来替代水平布线系统中的铜缆方案。光纤收发器不仅大大简化局域网的升级,而且可以保护原有铜缆LAN设备的投资,成为当前市场的迫切需要。自适应10/100Mbps快速以太网收发器能够很好地满足网络带宽的平滑升级,解决网络拥塞问题,具有较高的性价比。 100Base-T,100Base-FX标准,能够有效地支持全双工或半双工的工作方式,是校园和骨干网或交换共享以太网整体布线环境中的理想器件。可以用于连接服务器、工作站、HUB、交换机,它有单模和多模两种光纤传输模式。本设计基于以上特性,设计的是10/100Mbps光纤收发器。

Abstract
The optic fiber es to be the ideal transmit medium in all kinds of application since the seventies, which rely on its own characteristic (such as being free interruption by noise, privacy the fine and high transmit by bandwidth, etc). In recent years, with the standard of connecting changing, the development and using of the gradual of the bandwidth of photoelectric device, optical cable, connector technology and the bandwidth’s updating step by step, more and more users begin to use “optic fiber reaching tabletop” and substitute the copper cable scheme of horizontal wiring system. Optic fiber transceiver not merely simplifies the upgrading of the LAN greatly, and can protect the investment of the original copper cable LAN equipment, which es the urgent needing of the present market. 10/100Mbps adaptive fast transceiver meets the level and smooth upgrading of the bandwidth of works, solves the congested problem of work, has good performance and not much cost. It supports 100Base-T, 100Base-FX standard, can support all core half a duplex working way effectively. It is the ideal device in the environment of campus, the work and the wholly changing share . It can be used to connect server, workstation, HUB, exchanger and so on. And there are two kind of optic transmit mode --single mode and multiply mode. This dissertation addresses the above issues and design one simple 10/100Mbps adaptive optic fiber transceiver.
