S-531Pen Style Visual Fault Locator
1. Summary:
The S-531 Visual fault locator has two light output modes: continuous light (CW) and 1Hz frequency of light. It will display the output mode through the indicator. The metal shell material and small size will be portable to carry.
2. Features:
a.High power laser and visible 650nm red light
b.Anti-collision shell
c.Pen style design to make it easy to carry
d.Continuous light or 1Hz frequency of light output
e.applicable for SM and MM fiber (Single-mode, multi-mode fiber)
f.Universal alkaline battery
g.Continuous working time more than 40 hours
3. Application
a.Insert the fiber into VFL through Fiber Connector. It can be used as reference of the multi-core cable
b.End to end fiber identification
Identify the breaks and micro-bend of the pigtail/fiber
c. OTDR dead zone fault locator: check the fiber fault point which OTDR can't find (breakpoint, the beginning and the end of the fiber properties, and also the high loss section due to the microbending, for example: fiber optic patch cords, pigtails, the optical fiber core wire in junction box or bare fibe, etc
d.Identify the certain distance of fiber according to the power. Such as 10mw pen style VFL can check the distance up to 10kms
4. Keypad
This LED indicator shows the following working mode:
1) power on indicator(red)
2) 2Hz ,9Hz frequency indicator(red and winking)
3) power off ( indicator runout)
5. Operation
a.Take off the dust-proof cap
b.Clean the Fiber connector before test
c.Connect the fiber's adapter to the output port of visual fault locator
d.Press the button to start the testing, users would visually find the broken and micro bends
e.Press this button to inject 2Hz,9Hz modulation to the tested fiber
f.Press this button again to turn off the unit.
g.Take out the fiber and cover the dust proof cap of visual fault locator
