Overview
The FiberXP FR-FCUSCUS21000M Single Mode OTDR Fiber Ring is an essential tool designed to minimize the OTDR dead zone and allow for accurate measurement of both near-end and far-end connectors of a fiber link. By providing a controlled launch condition, this fiber ring ensures that the initial event is clearly visible and measurable without the saturation effects common in testing short fiber spans.
Engineered for portability and durability, the unit features a compact, lightweight housing complete with a repositionable carabiner for easy attachment to technician belts or test gear. This one-fiber configuration includes 1000 meters of high-quality Corning single-mode fiber, ensuring reliable performance in field testing environments.
