Loss Testers & Fault Locators

Loss testing and fault locating are pivotal processes in maintaining optimal performance within fiber optic networks. During loss testing, precise measurements of signal loss are conducted using specialized equipment such as optical loss test sets, power meters, and light sources. These tools collectively assess the efficiency of signal transmission through optical fibers and connectors, ensuring adherence to desired standards. In fault locating, issues such as breaks, bends, or abnormalities in the fiber optic cable are identified using Visual Fault Locators (VFLs) and other dedicated tools. These instruments allow technicians to pinpoint faults with accuracy, facilitating swift and effective troubleshooting. Our inventory includes advanced optical loss test sets, power meters, light sources, and VFLs, equipping technicians with the tools needed for meticulous loss testing and efficient fault location, thereby enhancing the reliability and performance of fiber optic communication systems.
