How to test fiber optic cables without using patch cords

Home / How to test fiber optic cables without using patch cords

The three standard methods for testing fiber optic cabling are a visible light source, power meter and light source, and optical time domain reflectometer (OTDR). Fiber optic testing ensures the performance and reliability of fiber optic networks. While there are many different fiber optic cable tests, the most common version is an insertion loss test, also known as an attenuation, jumper, or connectivity test. This test requires a special testing kit and protective eyewear, but it will help you diagnose problems with the cable's.
