Fiber Optic Cable Testers

Our Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without any damages to the bend fiber. When the traffic is present, the intermittently audible tone is activated.


This optical fiber identifier also recognizes the modulation like 270Hz, 1kHz and 2kHz. When they are used to detect the frequency, the continuously audible tone is activated. There are four adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0. This optical fiber identifier is powered by a 9V alkaline battery.
