OFI-3 ოპტიკური ბოჭკოს იდენტიფიკატორი

OFI-3 optical fiber identifier is a low cost, portable instrument designed to detect optical signals without disrupting online service. During installation and maintenance of optical network, it's often necessary to isolate a specific fiber, By simply clamping the OFI-3 on a fiber. The OFI-3 will indicate if there is a signal, the direction, the intensity and the modulation frequency.
