Product Description

Field Use Non-Invasive Live Fiber Detection Optical Fiber Identifier

The Optical Fiber Identifier is a non-invasive handheld tool used to detect live optical signals in single-mode fiber cables without disconnecting the fiber. By gently bending the fiber and detecting light leakage, it accurately identifies active transmission, signal direction, and modulation frequency (270Hz / 1kHz / 2kHz), making it ideal for field technicians during troubleshooting or maintenance.

Features

Applications

 

• Non-destructive live fiber detection;
• Detects 1310nm, 1490nm, 1550nm, 1625nm;
• Identifies signal modulation (270Hz/1kHz/2kHz);
• Directional indicator + audible beep alert;
• Universal clamp head for 250µm–3.0mm fibers;
• Long battery life, portable design.

• In-service fiber identification;
• Live fiber testing without service disruption;
• FTTH fiber route tracing;
• Telecom maintenance in field operations;
• Signal presence checking before disconnection;
• Passive optical network troubleshooting.
