摘　　要：介绍了ITU-T新发布的用于陆地传输的大有效面积、低损耗的G.654E光纤,综合比较了该光纤在衰减、有效面积、几何尺寸、熔接以及成缆工艺等方面和常规G.652光纤的差异;重点探讨了该光纤在电力通信中的应用前景,详细分析了光纤有效面积增大及衰减降低对拉曼放大器泵浦效率和系统OSNR性能的影响,并在此基础上探讨了G.654E光纤在电力通信中的应用方向。We introduced the new released G.654E fiber by ITU-T with large effective area and ultra low loss performance, and compared this fiber with legacy G.652 fiber from paralneters of attenuation, effective area, MFD, cutoff wavelength, splicing loss and cabling process. We also discussed the application scenarios of this fiber in power communication system, and analyzed the influence of effective area and attenuation of fiber on pump efficiency of Raman amplifier and OSNR perfornlance of system in detail. On this basis, the application direction of G.654E fiber in power communication is discussed.
