Product Description

Handheld Fiber Tool Kits Visual Fault Locator VFL 20MW 650nm SC FC ST 40 KM





Pen-type light /laser pen is easy to operate,convenient to carry.It can be used to do visual test for fiber,

cable or connector. When the tested fiber have a breakage,the transmission laser will leak out at that 

place,then you can know where the fiber damage is. This way is available for single mode or multimode.

It is one of the necessary fiber test tools for site operation worker and fiber maintenance personnel.



Our light pen advantage


1. light pen don’t have fiber coupling inside, so the fiber end face separate with fiber pen to avoid direct 

     contact (if direct contact, fiber pen end face is easy to dirty, should clean the fiber again).

2. sufficient power (1-50mW, no less than the power show on the label).

3.  the housing is insulate, excellent anti-static effect.




  1. fiber breakage, bending fault locating;
  2. OTDR dead zone fault checking;
  3. end to end fiber identification;
  4. optimization of mechanical splice point
