Fiber Identifier Suitable for 0.25/0.9/2.0/3.0mm Traffic Direction Live Fiber


This Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without any damages to the fiber. When the traffic is present, the intermittently audible tone is activated.
The optical fiber identifier also recognize 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: 0.25mm, 0.9mm, 2.0mm and 3.0mm fiber cables.
