Overview
The AFL FR-SMF-1000-USC-UST Fiber Ring is an OTDR launch cable designed to assist in accurate fiber optic network characterization. By providing a controlled length of fiber between the OTDR and the link under test, it allows for the measurement of the insertion loss and reflectance of the near-end connection that would otherwise be masked by the OTDR's initial dead zone.
This assembly features 1000 meters of standard G.652 single-mode fiber housed in a rugged, lightweight, and compact ring. It is ideal for broadband and long-haul fiber network testing, including FTTH applications where precise validation of link integrity is required.

Frequently Asked Questions
What is the purpose of an OTDR fiber ring?
It acts as a launch or receive cable to bridge the OTDR dead zone, enabling the measurement of loss and reflectance at the near-end and far-end connections of a fiber link.
What type of fiber is used in this ring?
This model uses standard G.652 single-mode fiber.
Can I use this for FTTH testing?
Yes, it is designed for broadband and FTTH network testing applications.
What does the connector configuration mean?
The SC and ST designation indicates the specific connector interfaces on the launch and receive ends of the 1000m fiber length.
Is the case included?
Yes, the fiber comes organized in a rugged and lightweight case designed for field portability.
