Overview
The FiberXP® FR-STSCAS2-1000M Single Mode ST/UPC to SC/APC Fiber Ring OTDR Launch Cable is designed to work with an Optical Time-Domain Reflectometer (OTDR) to effectively minimize the instrument's event dead zone. By serving as both a launch and receive cable, it enables accurate measurement of both the initial near-end and far-end connectors of the fiber link under test.
Constructed with 1000 meters (3281 feet) of genuine Corning 9μm single-mode fiber, this launch ring is housed in a portable, lightweight, and durable pouch. It features 1-meter pigtails and a repositionable carabiner for easy attachment and transport in various field environments.
