在建立了一套光纤系统之后,必须注意测试其中的三个关键部件:发射器、接收器和互连用光纤。只要用两项工具,即一台光学时域反射计(OTDR)和一台光学功率计,就可以测试光纤系统,不必使用大型台式仪器。了解这两种仪器,可以帮助我们正确使用,并使我们知道它们能够测量光纤系统的那些性能。必须检查光纤系统的第一部分,
After setting up a fiber optic system, one must pay attention to testing three of the key components: transmitters, receivers, and interconnecting fibers. With just two tools, an Optical Time Domain Reflectometer (OTDR) and an optical power meter, you can test your fiber system without using a large benchtop instrument. Understanding both instruments helps us to use them correctly and lets us know that they can measure those properties of fiber systems. The first part of the fiber system must be checked,
