LASER FAULT LOCATOR

-Visible red laser deisgned to inject visiblelight energy into a fiber.  

-If there are sharp bends, breaks and faulty connectors and other leak, red light allowing technicians to visually check and detect.

- This is an ideal tool for locating large number of defects that are hidden in OTDR's Blind spots or dead zone. 

  *2 TYPE OF VISUAL FAULT LOCATOR*

1. PEN TYPE VFL: small in size, easy to carry 
2. HAND HELD VFL: large in size and weight is much more higher than pen type.

How to Use VFL

• Remove the plastic connector covers from both ends of the test fiber cable.
• Connect the fiber optic visual fault locator one end of the fiber. Press the tester button and observe that light emanates from the other end of the fiber. This gives a simple indication of the continuity of the fiber link.
• Repeat with several other fibers. Check for light that can be seen leaking from a faulty splice. This may illustrate an easy way of carrying out visual fault finding on bad splices or joints.
• Disconnect all equipment, put the plastic covers back on the connector ends and return everything to the state it was in before you started the practical so that the next group can carry out the practical in full.
