Overview
The FiberXP FR-LCALCUS21000M is a single-mode OTDR launch cable designed to minimize the impact of the OTDR's instrument dead zone. By providing an initial reference point, it allows technicians to accurately characterize the near-end connection and the far-end connection of the fiber link under test.
This unit features 1000 meters of high-quality Corning single-mode 9µm fiber configured in a compact, portable ring design. It includes 1-meter pigtails and a repositionable carabiner for convenient attachment to test equipment or field gear, making it ideal for field fiber testing and certification in various network environments.

Frequently Asked Questions
What is the purpose of an OTDR launch cable?
An OTDR launch cable is used to bridge the gap between the OTDR and the fiber being tested, allowing the OTDR to resolve the near-end connection and measure the total length of the fiber link without signal dead zone interference.
Is this compatible with APC connectors?
Yes, this model features LC/APC connectors for reduced back-reflection, which is critical for accurate single-mode testing.
What type of fiber is used?
This unit uses 9µm Corning single-mode fiber to ensure reliability and compatibility with telecommunications standards.
How is the fiber protected during transit?
The product comes in a durable pouch designed to protect the fiber ring from environmental hazards during transport between jobsites.
Does this include a way to mount it to my test gear?
Yes, it features a repositionable carabiner that allows you to clip the ring directly to your OTDR or tool bag.
