Visual Fault Locator, It could be regarded to be part of OTDR but the fiber fault locator is much cheaper
Fiber visual fault locator is a kind of device which is able to locate the breakpoint, bending or cracking of the fiber glass. It can also locate the fault of OTDR dead zone and make fiber identification from one end to the other end. Designed with a FC,SC,ST universal adapter, this fiber optic visual fault locator is used without any other type of additional adapters, it can locates fault up to 10km in fiber cable, with compact in size, light in weight, red laser output.
Fiber visual fault locators include the pen type, the handheld type and portable visual fiber fault locator. FiberCasa also supply a new kind of Fiber laser tester, it can locates fault up to 30km in fiber cable.
When choosing a visual fault locator, there are several tips for you.
(1)Focus on the launching power and launching range.
Launching power is the lowest power it needs, and launching range it the distance it can detect.
VSL-8 series visual fault locator with 4 launching range, are 5km,12km,14km and 15km. The launching power are 1mW,10mW, 15mW and 30mW.
(2)The size and weight
Visual fault locator is a common and easily fiber tester, it can be used in many area and many position ,so a small size and easily taking is very important.
The human engineering design and its small size give you better feeling of handle. And with the composite plastic shell,it’s super light and easy be taken.
（3）The stability.
The stability is the most important part of a visual fault locator. When a visual fault locator without a stability light source, it can’t work well and please leave it alone.
Visible laser Source is same to Visual Locator. VSL-8 series visual fault locator is d with human engineering design. With its advanced PCB circuit Design, the light of VFL-8 won’t get dim even in a low battery. It using auto power control circuit to make the output laser power more stable.
