摘　　要：针对G.654.E光纤的截止波长大于喇曼泵浦波长是否对系统性能造成影响的问题,实际测试和理论分析了G.654.E光纤的喇曼增益系数,并通过对实际喇曼放大系统,验证了G.654.E光纤较长的截止波长并不会对喇曼增益造成明显影响。相比于G.652.D,G.654.E光纤具有超低损耗、大有效面积及低的自熔熔接损耗,不仅能提升系统光信噪比(OSNR)且具有更佳的综合系统性能,可适用于陆地喇曼放大系统。Aiming at the problem whether the cut-off wavelength of G.654.E fiber is larger than the Raman pump wavelength,and whether it will affect the system performance,the Raman gain coefficient of G.654.E fiber is measured and theoretically analyzed.The long cut-off wavelength of G.654.E fiber has no obvious effect on Raman gain through the practical Raman amplification system.Compared with G.652.D,G.654.E fiber has ultra-low loss,large effective area and low self-fusion loss.It can not only improve the optical signal noise ratio(OSNR)of the system,but also have better integrated system performance.It can be applied to land Raman amplification system.
