Overview
The AFL FR-SMF-150-ULC-USC Fiber Ring is a specialized OTDR launch cable assembly designed to facilitate accurate fiber optic network testing. By providing a controlled length of fiber, it allows an OTDR to measure the insertion loss and reflectance of the near-end and far-end connections of a link under test.
This assembly features 150 meters of G.652 standard single mode fiber, housed in a durable, compact, and lightweight protective case. The enclosure is designed for portability, ensuring it can easily be integrated into standard fiber optic test kits and OTDR carry cases for use in various premises network environments.

Frequently Asked Questions
What is the purpose of an OTDR fiber ring?
An OTDR fiber ring acts as a launch or receive cable, allowing the OTDR to compensate for the dead zone at the beginning of a test and verify the performance of the first and last connectors in a fiber link.
Can I use this for multi-mode fiber testing?
No, this unit is specifically configured for single mode (G.652) fiber applications.
Is the case durable enough for daily field use?
Yes, the unit features a rugged and lightweight case specifically designed for field protection and easy integration into technician tool kits.
What is the length of the fiber in this ring?
This model contains 150 meters (492 feet) of single mode fiber.
Does this include both connectors?
Yes, this model features an LC connector on one end and an SC connector on the other.
