Overview
The FiberXP FR-FCFCAS2-150M Single Mode Fiber Ring is a specialized OTDR launch cable designed to minimize the impact of the OTDR dead zone during fiber optic network testing. By acting as a launch and receive cable, it allows technicians to accurately measure the insertion loss and reflectance of both the near-end and far-end connectors of the fiber link under test.
This compact, lightweight unit features 150 meters of high-quality 9µm Corning single mode fiber. The design includes 1-meter pigtails for easy connection and is housed in a durable, portable pouch that includes a repositionable carabiner for convenient field deployment.
Key Features
-
Dead Zone Minimization
Enables accurate testing of the initial near-end and final far-end connectors by extending the test reach beyond the OTDR dead zone. -
High-Quality Fiber
Constructed using genuine Corning 9µm single mode fiber to ensure consistent and accurate signal transmission. -
FC-FC/APC Configuration
Features industry-standard connector types to support compatibility with a wide range of test equipment and fiber patch panels. -
Compact Design
The ring structure measures 5-1/4" x 1", providing a portable solution that saves space in technician tool kits. -
Integrated Pigtails
Includes 1-meter pigtails that provide flexibility during installation and testing procedures. -
Durable Storage
Supplied with a protective pouch that shields the fiber ring from environmental damage and simplifies transport. -
Repositionable Carabiner
Allows for secure attachment to work belts or equipment cases, ensuring the unit remains accessible in the field.
Applications
- OTDR testing of single mode fiber networks
- Measurement of near-end connector loss

Frequently Asked Questions
What is the purpose of an OTDR fiber ring?
It is used as a launch cable to allow the OTDR to overcome the initial "dead zone" and successfully measure the loss of the first connector in a link.
Is the fiber compatible with single mode networks?
Yes, it uses Corning 9µm single mode fiber specifically designed for single mode testing.
Are the connectors interchangeable?
No, the unit comes pre-terminated with FC and FC/APC connectors as specified in the model number.
Does it come with a storage case?
Yes, it includes a durable pouch for storage and protection.
Can I use this for multimode fiber?
No, this product is designed specifically for single mode fiber applications.
