OFI-50A Cable Identifier

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.
