1 前 言 上一章着重介绍了利用光缆及相关器件进行光线路设计与施工的知识。本章拟就施工后光线路的测试作一介绍。 光线路施工后的测试,主要有传送损耗测量和接续损耗测量两个项目。本章同时拟就测试中经常使用的“光时域反射计(OTDR)”的操作、运用实例作一说
1 Preface The previous chapter focused on the use of optical fiber cables and related devices for optical line design and construction knowledge. This chapter intends to introduce the testing of the light lines after construction. Optical line construction after the test, there are two main transmission loss measurement and measurement of loss. This chapter also intended to test the often used “OTDR ” operation, the use of examples to make a statement
