<p>Fiber requires a different class of diagnostic tools due to its precision and sensitivity. In this episode, we cover devices like OTDRs (Optical Time Domain Reflectometers), power meters, and visual fault locators. You’ll learn how these tools detect breaks, signal loss, and connector issues with pinpoint accuracy. OTDRs, for example, send pulses of light and measure reflections to map out the fiber’s health over long distances.</p><p>We also cover best practices for cleaning, inspecting, and handling fiber connectors, which are highly susceptible to contamination and damage. Fiber optics are critical for high-speed backbone connections, and small problems can cause big performance hits. This episode gives you the tools and techniques needed to verify fiber performance and quickly resolve outages.</p>
