Overview
The FiberXP FR-SCULCUS21000M Single Mode SC to LC Fiber Ring OTDR Launch Cable is a critical tool designed to minimize the OTDR event dead zone. By providing a controlled length of fiber at the beginning and end of a link, it enables accurate testing of near-end and far-end connectors that would otherwise be obscured by the instrument's initial pulse.
This launch cable features a compact, portable ring design equipped with a repositionable carabiner for easy attachment to technician belts or test gear. Constructed with 1000 meters (3281 feet) of high-quality Corning single-mode 9µm fiber, it is protected within a durable pouch for field use, ensuring consistent performance in diverse network installation and maintenance environments.
