FI-60 Live Fiber Identifier

Live Fiber Identifier with Integrated Optical Power Meter

Inadvertently disconnecting active fiber during installation, test and troubleshooting is a common cause of dropped service. The new FI-60 LFI enables users to easily detect the optical signal without having to disconnect the fiber or disrupt network traffic. The unique VIAVI Solutions® SafeChekTM system ensures safe and repeatable engagement with most fiber types, without the hassle of changing out costly dies.
The FI-60 easily converts to an Optical Power Meter (OPM), providing twice the value for your investment and reducing the number of tools you have to carryon the job.
