【Widely Compatible】The 2.5mm universal connector and included LC adapter make the detector compatible with ST, SC, FC, and LC connectors, and can be used with different circular and square optical cables.

【Effortless Fault Detection】The visual fault locator accurately detects and locates fiber breaks, poor connections, bending or cracking. Emitting a strong 650nm light, faults in the optical fiber refract the light, providing an easy way to locate the problem.

【Long-distance Output】With its powerful output and strong red light, the VFL can detect faults up to 40-50 kilometers away in fiber optic cables. The efficient power supply circuit ensures stable power output.

1.《Cable Length Test》Accurately measure the cable length without calibration, and the range is 1-500 m. It can detect the cross, short circuit, and open circuit of cables.

2.《Scanning Modes》Three scanning modes can be selected: normal mode/anti-interference mode/PoE mode.

3.《Port Flashing》Through the flashing port indicator on the hub/switch, the hub flashes to locate the network port, which can quickly find the network cable on the switch/router. It can be used for 10M/100M/1000M hubs/switches.
