Overview
The FiberXP® FR-FCSCS2-500M Single Mode FC to SC Fiber Ring OTDR Launch Cable is a specialized tool designed for fiber optic network testing. By providing the necessary length for an OTDR to settle, this launch cable minimizes the effect of the instrument's event dead zone, allowing for precise characterization of the near-end connector.
Engineered for portability and durability in field environments, this unit features a compact, lightweight ring housing that includes a repositionable carabiner for easy attachment to technician gear. It is supplied with 500 meters (1640 feet) of high-quality Corning single-mode fiber in a 1-fiber configuration, finished with 1-meter pigtails. The system is protected by a rugged zipper pouch, ensuring the fiber and connectors remain clean and secure during transport and storage.
Key Features

Frequently Asked Questions
What is the purpose of an OTDR fiber ring?
An OTDR fiber ring acts as a launch lead to allow the OTDR to overcome its initial 'dead zone,' enabling the user to measure the insertion loss and reflectance of the first connector on the cable under test.
Is this compatible with all OTDR models?
Yes, this is a passive fiber optic tool and can be used with any OTDR equipped with FC or SC interfaces.
What fiber type is used in this ring?
This model utilizes standard 9μm single-mode fiber manufactured by Corning.
What is included with the purchase?
Each unit includes the OTDR fiber ring and a durable, protective zipper pouch.
Can this be used as a receive cable?
Yes, it can be applied as both a launch and a receive cable to measure both ends of a fiber link.
