## Overview

The Wilcom F6121R Ribbon Fiber Identifier is a lightweight, rugged tool designed for fast, accurate, and non-destructive identification of optical fibers. It detects live fiber signals and traffic direction using audible tones and LED indicators, supports multiple adapter heads for ribbon and patch cords, and ensures maintenance without service interruption.

## Description

The Wilcom Model F6121R Ribbon Fiber Identifier is a lightweight, rugged, easy-to-use installation and maintenance instrument designed for fast, accurate identification and traffic testing of optical signals without cutting the fiber cable or interrupting service. By utilizing local detection technology (non-destructive macro-bend detection which does not damage or overstress the fiber), this unit is ideal for use during routine maintenance and line modification, and can be used to locate a particular fiber line, non-obtrusively identify live fibers, and determine whether traffic is present. The Ribbon Fiber Identifier detects low frequency tones at 270 Hz, 1000 Hz and 2000 Hz. When traffic is present on the fiber under test, an audible tone can be heard as well as the traffic direction which is indicated by LEDs illuminating on the probe. During installations, maintenance, rerouting, or restorations it is often necessary to isolate a specific fiber without disrupting service. A light source such as Wilcom's Model FS1316 used in conjunction with the Ribbon Fiber Identifier can make the job a lot easier. The Ribbon Fiber Identifier includes three easy to use field changeable adapter heads. Two adapter heads are dedicated to ribbon fiber making the unit ideal for verifying signal presence or absence (live or dark fiber) on ribbon fiber. One adapter head is for use on Bare Ribbon Fiber, and the other adapter head is for use on Jacketed Ribbon Fiber. The third interchangeable adapter head is for testing 3mm patch cords.Features and Benefits:Rugged Metal Case Field-proven lightweight rugged metal housing for years of heavy use.Audible ToneThe unit provides an audible tone in the presence of a fiber optic signal.
