ETA Fiber Optics Installer Certification Practice Test 2025 – Complete Exam Prep

Continuity testing is a fundamental procedure in the installation and maintenance of fiber optic cables. This test determines whether light can transmit through the fiber from one end to the other, verifying that the fiber is properly connected and functional. It helps identify breaks, bends, or faults in the cable that could disrupt signal transmission.

This testing is essential for ensuring that the fiber optic installation will perform as expected, allowing technicians to diagnose issues before they lead to more significant problems in network performance. The use of light sources at both ends of the fiber and a power meter or visual fault locator provides a straightforward method for confirming that the fiber path is intact.

Other testing methods, although relevant in their contexts, do not specifically address the integrity and functionality of the fiber optic cable itself. Speed tests assess data transfer rates through the fiber once installed, while electrical current and network security assessments are more applicable to network equipment and overall system performance rather than the fiber optic medium itself.
