近年来,国外光纤光缆测量技术发展迅速,测量方法和设备甚多.有些测量技术日臻成熟,从试验室走向定型投产.在测量标准方面,发展初期,各国及其国内各厂、所大都“各自为政”,现已开始拟定统一的国际规格标准.随着光纤通信系统的实用化,除了传输损耗和传输带宽外,先后开展了传输函数、远端串音、模变换、模耦合、相于偏振特性等参数的研究.同时出现了研制综合参数测试仪和现场便携式测试仪的苗头.资料[1]概要地介绍了传输损耗、脉冲展宽和折射率分布等参数的各种测量原理、方法和装置图,集中讨
In recent years, foreign fiber optic cable measurement technology has developed rapidly, many measurement methods and equipment.Some measurement technology is maturing, from the laboratory to the stereotypes put into production.In the measurement standards, the early stages of development, countries and their domestic plants, mostly “fragmented ”, Has begun to develop a unified international standards.With the practical application of optical fiber communication system, in addition to transmission loss and transmission bandwidth, has carried out the transfer function, remote crosstalk, mode conversion, mode coupling, phase polarization characteristics And other parameters at the same time developed a comprehensive parameter testers and field portable testers signs.Data [1] introduced the transmission loss, pulse broadening and refractive index distribution and other parameters of the various measurement principles, methods and device diagrams Focus on discuss
