Product Description

OFI-3 High Performance Optical Fiber Identifier , Live Fiber Optical Identifier 900~1650nm


Gerneral Description:  
The OFI-3 Optical Fiber Identifier is a low cost, portable instrument designed to detect optical signals without disrupting traffic. Based on non-destructie macrobending technology, the OFI-3 doesn\'t disrupt traffic, damage or oerstress 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 OFI-3 onto a fiber, the OFI will indicate if there is a signal, a modulated signal, or traffic and show signal direction.


♦   Detect a variety of optical tones,270Hz,1kHz and 2kHz 
♦   Powered by 2 units of 1.5 AA alkaline batteries(not included)
♦   RB0.25mm,RB0.9mm,RB3.0mm plungers available
