When you tap the target cable at a remote location, the device at the near end can clearly “hear” and “see” this distinct vibration signal, allowing it to accurately identify the target cable from among multiple parallel ones. In fiber optic network maintenance, rapidly and accurately pinpointing a fault is crucial for minimizing service outage time and improving operational efficiency. Traditional methods rely on OTDR distance measurement followed by manual inspection, which is time-consuming and labor-intensive. This. How to efficiently troubleshoot optical cable line faults and quickly obtain optical cable pigtail resource information has become a key point of user needs. It converts the. FTS-900 optical cable routing fault intelligent locator can find and locate buried optical cables and pipeline optical cables, generate specific location data of optical cable joint box, breakpoint location and light attenuation, provide protection support services for optical cable line and. Non-Destructive Tracing: Uses optical interference technology to identify cables and faults without cutting, bending, or freezing the fiber, ensuring operator safety. 3-in-1 Versatility: Combines Fault Tracing, Cable Identification (Knocking), and full OTDR functions in one device for complete. Fiber optic cables are critical components of modern communication infrastructure, often buried underground for protection and durability.
