You can answer how do you test fiber optic cable with three main techniques. You use an OTDR to check for faults and length. There are three main principles that needs to be taken in consideration for an efficient optical connection: a perfect core alignment, perfect physical contact and dirt-free connectors. Polished connector ferrules require visual inspection during manufacturing to evaluate polishing and find possible defects during the connector termination process. But to ensure optimal performance, you should maintain their integrity by testing them regularly. What do fiber testers do? Which fiber tester is right for you? In. 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.
