摘要
利用国产１．４８μｍ泵浦ＬＤ和优质掺饵光纤研制了一种实用化的掺饵光纤放大器，小信号净增益２８ｄＢ，噪声系数５．１ｄＢ，增益谱宽大于２０ｎｍ，最大输出功率达４．８ｄＢｍ和１１ｄＢｍ。实验研究了ＥＤＦＡ在ＦＭ／ＦＤＭ模拟电视光纤系统的应用，利用ＥＤＦＡ作为系统的功率提升和中继放大器，分别成功地进行了１８５ｋｍ和２２４ｋｍ的系统传输试验。
We have developed an EDFA using the home made 1. 48μm LDs as pump sources and high-quality erbium-doped fibers, which has net small signal gain 28dB, noise figure 5. 1dB, bandwidth more than 20urn, and the maximum output power 11dBm. Its application in FM/FDM analog optical video system is studied. The 185km and the 224km transmission experiments are respectively demonstrated using the EDFA as a booster and a in-line amplifier.
