Optical Fiber Identifer - China

price: contact company for price

The FST-3 Optical Fiber Identifier is a low cost, portable instrument

designed to detect optical signals without disrupting traffic. Based on

non-destructive macrobending technology, the FST-3 doesn’t disrupt

traffic, damage or overstress the fiber, enabling efficient, accurate

and reliable data acquisition. During maintenance, installations,

rerouting or restorations, it’s often necessary to isolate a specific

fiber. By simply clamping the FST-3 onto a fiber, the FST will indicate

if there is a signal, a Modulated Signal, or traffic and show signal



Detect a variety of optical tones, 270Hz, 1kHz and 2kHz

Powered by 2 units of 1.5V AA alkaline batteries

RB0.25mm, RB0.9mm, RB3.0mm plungers available
