OFI–50A uses optical fiber sensing principle to confirm the target fiber; It can quickly identify deep buried, overhead and pipe fiber cable without any destroy, and provide a simple method for maintenance personnel. Users only need gently knock on cable, when knocking to the target cable, OFI-50 can clearly hear the knock from earphone, which can accurately identify the target cable.

OFI–50A is real one-key type test; handheld design, easy to carry, 3.5' color screen real-time waveform; the software of the intelligent struck the judgment of the two operation / display mode, combined with the Headset real-time audio, with 3 kinds of recognition percussion method, so as to quickly and accurately identify the measured cable.


●  Easy to use, reliable

●  Fast identification of deep buried, overhead and pipe fiber cable

●  Built-in intelligent mode, knock in the measured cable screen showed positive and negative Pyramid strength; output the notification sound

●  Rapid and accurate identification

●  Click the targeted or wanted cable, OFI-50A can response with sound and light reaction

●  According to the Headset feedback information, the operator can intuitive judgment percussion cable

●  According to the waveform real-time cable, knock in the measured cable real-time waveform will have obvious wave, visual disturbance

●  VFL function is available

●  Non destructive optical cable
