1. Description:
The MPO Tester is a very useful tool designed for
checking the defects of a MPO arrayed fiber cable or
MPO Connector. The MPO emits a visible 650 nm
wavelength visible red laser light through fiber optic
cables, then if there are breaks or defects in the fiber will refract the light,
creating a bright glow around the faulty area.
The LD output signal can be all 12 Fibers switched to CW Mode to obtain
different visual effects.
2. Features:
Easy to check fiber faults by using 650 nm visual red laser
Range: visibility up to SMF or MMF Fiber 1 km
12F MPO Connector for testing additional
Highly effective power circuits designed for stable laser power
Operating in Continuous Wave (CW) Mode or Pulse Mode
Driven by external USB with power bank battery

5. Operating Manual
1. To connect MPO Tester to USB to charge the internal battery.
2. Connecting the MPO fibers (DUT, Device Under Test ) to the MPO Tester
Adapter.
3. Turn on the MPO tester
4. To check if the MPO fibers all shown red dots, that means, the MPO fibers
performed well and fine.
6. To turn off the MPO Switch
7. To disconnect the DUT for MPO Adapter.
8. You can switch the Mode to CW ( Continuous Wavelength ) Mode or Pulse
Mode.
9. To disconnect the USB.
10. To store the MPO Tester properly.
