【摘要】：促使光通信產(chǎn)業(yè)快速發(fā)展的核心性器件是摻鉺光纖放大器(erbium-doped fiber amplifier,EDFA),亦是全光型光先通信得以實現(xiàn)的不可或缺的主要器件。在最近幾年中,隨著通信業(yè)務多元化的持續(xù)發(fā)展,通信與信息技術也隨之快速發(fā)展,與此同時對摻鉺光纖放大器(EDFA)的功能特性也提出了更高的要求。在緊密波分多用(dense wavelength division multiplexing,DWDW)系統(tǒng)、有線電視網(wǎng)絡(Community Antenna Television,CATV)等系統(tǒng)中,EDFA都起著非常重大的作用。EDFA對網(wǎng)絡中的信號進行沒有光-電轉換過程直接的放大,使得EDFA具有如下優(yōu)點：高增益；寬頻帶；小噪聲指數(shù)；大功率等。 對摻鉺光纖放大器的改進設計,在本文中的討論有下列內(nèi)容： 1.論文分析討論了光網(wǎng)絡中EDFA的框架構成、組成結構、基關鍵技術、研究現(xiàn)狀以及發(fā)展方向。 2.采用粒子群改進算法(PSO)對光絡中的S波段、C波段及L波段EDFA進行改進設計,最后得到了具有優(yōu)良平坦度增益的C波段大增益(25dB)、小噪聲(5dB)EDFA和L波段高增益(25dB)、低噪聲(5dB)EDFA以及S波段大增益(10dB)、小噪聲(5dB)EDFA的改進設計,同時給出了EDFA結構參數(shù)的解決方案。 3.對EDFA的平坦化增益現(xiàn)階段采用的2種辦法(改進設計自身平坦增益的EDFA及引進平坦增益增益濾波EDFA)的研討現(xiàn)狀給予了一定描述,并對它們的優(yōu)缺點分別予以簡介。 4.采用DSP芯片技術結合PID算法,實現(xiàn)了摻鉺光纖(EDFA)泵浦的增益自動掌握,使得電路具有結構簡潔、擴容容易、更加可靠和便于實現(xiàn)等的特點。
[Abstract]:Erbium-doped fiber amplifier (erbium-doped fiber amplifier,EDFA) is the core device to promote the rapid development of optical communication industry. It is also an indispensable part of all-optical pre-communication. In recent years, with the continuous development of the diversity of communication services, communication and information technology has also developed rapidly. At the same time, the functional characteristics of erbium-doped fiber amplifier (EDFA) have been put forward higher requirements. EDFA plays a very important role in the systems such as compact wavelength division multipurpose (dense wavelength division multiplexing,DWDW) system and cable television network (Community Antenna Television,CATV). EDFA amplifies the signal in the network without direct optoelectric conversion process, which makes EDFA have the following advantages: high gain; Wide band; small noise index; high power, etc. The improved design of erbium-doped fiber amplifier is discussed in this paper as follows: 1. In this paper, the structure, key technology, research status and development direction of EDFA in optical network are analyzed and discussed. Particle swarm optimization algorithm (PSO) is used to improve the design of S-band, C-band and L-band EDFA in the optical network. Finally, the improved design of C band large gain (25dB), small noise (5dB) EDFA and L band high gain (25dB), low noise (5dB) EDFA, S-band large gain (10dB) and small noise (5dB) EDFA with excellent flatness gain are obtained. At the same time, the solution of EDFA structural parameters is given. 3. This paper gives a description of the current research status of the two methods of flatting gain of EDFA (improving the design of EDFA with flat gain and introducing EDFA of flat gain filtering), and introduces their advantages and disadvantages respectively. 4. By using DSP chip technology and PID algorithm, the gain of erbium-doped fiber (EDFA) pump is automatically controlled, which makes the circuit structure simple, easy to expand, more reliable and easy to realize.
