JFT-16 Optical Fiber Identifier
 JFT-16 Optical Fiber Identifier Detail:


Optical Fiber Identifier Specification

Optical Fiber Identifier Description:
Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without any damages to the bended fiber. When the traffic is present, the intermittently audible tone is activated. The optical fiber identifier also recognize the modulation 270Hz, 1kHz and 2kHz. When they are used to detect the frequency, the continuously audible tone is activatedThere are four adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0. The optical fiber identifier is powered by a 9V alkaline battery

Optical Fiber Identifier Features:
Easy-to-use with “ONE KEY” operation.
Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning.
Displays the relative core power
More accurate test with Sunshade
Easy-to-replace adapters
Durable metal housing and quality construction
Lower power indication
