Overview
The FiberXP® FR-FCSTM2-150M Multimode 50μm OTDR Fiber Ring is a specialized launch cable assembly designed to minimize the OTDR event dead zone during fiber optic testing. By providing a controlled length of test fiber, it enables technicians to accurately characterize both the near-end and far-end connectors of a fiber link.
Constructed with high-quality Corning fiber, this unit features a compact, lightweight ring housing designed for portability in field environments. It is equipped with 1-meter pigtails for easy connectivity and includes a repositionable carabiner for convenient attachment to test gear or technician equipment. The assembly is supplied in a durable protective pouch to ensure long-term maintenance and organization.
