把光纤系统用于大容量通信需要有精密的光纤光缆带宽测试方法。诸如光源特性和注入条件之类的各种因素会影响光纤带宽的测试结果。美国电子工业协会(EIA)和国际电报电话咨询委员会(CCITT)制订的准则旨在最低限度地减小这些潜在的测量误差。这些准则限定了光源的最大线宽和中心波长;推荐了实现标准注入条件用的搅模器技术或圆柱形滤模器技术。
The use of fiber optic systems for high-volume communications requires sophisticated optical fiber cable bandwidth testing methods. Various factors such as light source characteristics and injection conditions affect the test results of the optical fiber bandwidth. The guidelines developed by the EIA and CCITT are intended to minimize these potential measurement errors. These guidelines define the maximum line width and center wavelength of the light source; Dart or cylindrical filter technology is recommended for standard injection conditions.
