Overview
The FiberXP FR-SCSCM3-150M Multimode SC to SC Fiber Ring is a specialized OTDR launch cable designed to minimize the effect of the OTDR dead zone during fiber optic testing. By providing an additional length of fiber, it allows the OTDR to overcome the initial blind spot, enabling accurate measurement of both the near-end and far-end connectors of the fiber link under test.
This device features 150 meters (492 feet) of 50µm multimode fiber configured in a compact, portable ring design. It includes 1-meter pigtails for easy connection and comes equipped with a repositionable carabiner for convenient attachment to test equipment or belts. The unit is housed in a durable pouch, making it suitable for field deployment in diverse network installation and maintenance environments.
Key Features
-
150-Meter Fiber Length

Frequently Asked Questions
What is the purpose of an OTDR Fiber Ring?
It serves as a launch and/or receive cable to shift the OTDR's "dead zone" beyond the first and last connectors of the fiber link, allowing for accurate loss and reflectance measurements.
Is the fiber cable multimode or singlemode?
This model uses 50µm multimode fiber.
What type of connectors does this unit have?
This specific unit is configured with SC connectors on both the launch and receive ends.
How long is the fiber inside the ring?
The fiber ring contains 150 meters (492 feet) of fiber.
What is included with the product?
The product includes the fiber ring unit with pigtails and a durable carrying pouch.
