Overview
The FiberXP FR-SCASTUM2-1000M is a high-performance multimode OTDR fiber ring designed to minimize the dead zone of an optical time-domain reflectometer (OTDR) during fiber optic network testing. By serving as a launch and receive cable, it allows for accurate characterization of both the near-end and far-end connectors of a fiber link.
Constructed with 1000 meters of genuine Corning 50µm multimode fiber, this unit is housed in a portable, lightweight ring design. It is built for field environments and includes 1-meter pigtails and a convenient, repositionable carabiner for easy attachment to test gear or technician belts. The complete system comes protected in a durable pouch, ensuring longevity during transport and storage.

Frequently Asked Questions
What is the purpose of an OTDR fiber ring?
An OTDR fiber ring acts as a launch cable to provide sufficient length, allowing the OTDR pulse to stabilize and reveal events at the near-end connector that would otherwise be hidden in the dead zone.
Can I use this for single-mode fiber testing?
No, this specific model is designed for multimode fiber applications using 50µm core diameter fiber.
What connectors are installed on this unit?
This unit features an SC/APC connector on one end and an ST/UPC connector on the other.
Is the protective pouch included?
Yes, a durable pouch is included with every purchase to protect the fiber ring during storage and transport.
What is the length of the pigtails?
The unit features 1-meter pigtails for easy connectivity.
