EDFA 原理性能、生产工艺与失效原因分析摘要随着通信技术的进展，通信网络在工业数据传输中的应用日益增多。目前在工业数据传输领域大多采纳同轴电缆的通信方式进行，虽然经济有用，但在很大程度上限制了应用场合的拓展。为了使远距离的数据传输实现更灵活方便，本文选用 EDFA 技术进行远程数据的传输。EDFA 网络具有网络覆盖率高、速率快等优势，已广泛应用于电力、铁路、石油等行业，这必将成为工业控制与远程监测等领域的进展趋势。基于掺铒技术的 EDFA 系统主要由光模块和电模块组成，光模块完成核心的放大等功能，电模块完成相关的控制。模块的各组成部分的参数控制、工艺制程、失效模式是 EDFA 技术的关键。电模块的辅助使得 EDFA 的通信系统更易监控，本身的放大功能也更趋完善。通过讨论 EDFA 的核心技术，比较目前应用的各种放大模式，并通过分析目前的工艺与技术参数的实际控制，讨论 EDFA 的实效模式，以提高生产控制力，促使 EDFA模块的长远可靠性提升。关键词：EDFA，数据传输，通信系统，失效分析Principle of EDFA Performance, Production Process and Failure Cause AnalysisABSTRACTWith the development of communication technology, communication network in the application of industrial data transmission is increasing. At present ， using coaxial cable communication way mostly in the field of industrial data transmission, although the economic and practical, but largely limits the applications. In order to make the distance of data transmission to realize more flexible and convenient, this article selects the EDFA technology for remote data transmission. EDFA has network coverage rate is high, the fast rate of has been widely used in electric power, railway, petroleum and other industries, this will become a development trend of industrial control and remote monitoring, etc.EDFA based on erbium-doped system is mainly composed of optical module and electrical modules, optical modules to complete the core function such as amplification, electrical control module to complete rela...
