摘　　要：介绍光纤链路色散测量原理,提出一种针对链路色散测试仪的校准方法,并研制链路色散量模拟装置。实验结果表明:该装置所用光栅在波长1549.95nm左右满足色散平坦特性,完成0.1km长度色散光纤组仿真实际35km链路色散量。该方法为链路色散测试仪现场校准提供一种新的技术途径。The measurement principle of optical cable link dispersion is analyzed.A calibration method for link dispersion tester is proposed.The link dispersion quantity simulation device is designed and developed.The experimental results show that the grating used satisfies the dispersion flatness characteristic near the wavelength of 1549.95 nm,and the actual 35 km link dispersion is simulated by the 0.1 km dispersion fiber.A new technical approach is provided for on-site calibration of the dispersion tester.
