Visual Fault Locator & Fiber Identifiers

A visual fault locator (VFL) is an essential tool that quickly and easily locates problem areas in fiber cables. By pinpointing the exact location of fiber damage, technicians can diagnose, troubleshoot, and fix the problem efficiently.

FI-60 Live Fiber Identifier
The VIAVI FI-60 LFI enables users to easily detect the optical signal without disconnecting fiber or disrupting network traffic. FI-60 LFI also includes the unique VIAVI SafeChek system, which ensures safe and repeatable engagement with most fiber types without the hassle of changing out costly dies. The FI-60 also converts to an Optical Power Meter (OPM), providing twice the value for your investment and reducing the number of tools carried on the job.

  • Detecting an optical signal without having to disconnect the fiber 
  • Installation, service, maintenance, or troubleshooting 
  • Integration with FiberChekPRO for combined inspection and test reporting 

Key Features 

  • LFI head accepts multiple cable diameters (250 μm to 3 mm jacketed fibers) 
  • Durable metal input adapters (2.5 and 1.25 mm) for OPM 
  • Measures both absolute (dBm) and relative (dB) power 
  • Stores and recalls up to 100 OPM readings
