摘要
采用基于自相位调制(SPM)效应的连续波双频法对G.652.D光纤样品和多种G.654.E光纤样品的非线性系数进行了直接测量。结果表明具备大有效面积的G.654.E光纤非线性系数远小于G.652.D光纤,在降低非线性效应、提高传输系统光信噪比方面具有明显优势。从不同G.654.E光纤样品的测量结果来看,仅采用有效面积无法完整反映光纤的非线性性能,采用非线性系数可以对G.654.E光纤的非线性性能进行准确完善的评估。
Nonlinear coefficients of G.652.D fiber sample and many G.654.E fiber samples are measured directly by CW-SPM method.The measurement results show that compared with G.652.D fiber,G.654.E with a large effective area has a lower nonlinear coefficient,and it shows obvious advantage in reducing nonlinear effect and promoting OSNR of the optical transmission system.And the measurement results of different G.654.E fiber samples show that effective area alone can not evaluate fiber nonlinear performance completely. Nonlinear coefficient should be used to evaluate nonlinear performance of G.654.E precisely.
