The Insertion Loss Testing System of Main Optical Cable Based on Wavelength Division Multiplex

提出了一种基于波分复用的光纤光缆插入损耗测试系统,可以对光纤主缆的插入损耗进行测试,确保光纤主缆的性能。光纤主缆插入损耗测试系统由窄线宽激光光源、波分复用器、光纤主缆、光纤短接跳线、波分解复用器和光功率计组成。通过测试注入光纤主缆的输入光功率以及经过光纤主缆不同封装盒后的输出光功率,可以获得光纤主缆中不同光波长对应的插入损耗。在生产光纤主缆的过程中,该系统具备对光纤主缆中不同封装盒位置的波分复用器件盘绕产生的损耗进行在线监测的功能,可以提高光纤主缆的成品率和生产效率。

In this paper,the insert loss testing system of main optical cable based on wavelength division multiplex is proposed.The insert loss can be tested by the system to ensure the performance of the main optical cable.The insert loss testing system is composed of narrow linewidth laser light source,wavelength division multiplexer,main optical cable,optical short wire,wavelength division demultiplexer,and optical power meter.Through testing of input optical power and output optical power of the different wavelength,the insert loss of the main optical cable with the corresponding wavelength can be obtained.During the production process of the main optical cable,the testing system is able to on-line monitor the loss introduced by the coiled tail fiber of the optical cable integration.The proposed testing system is capable of improving the yield and the production efficiency of the main optical cable.
