Fiber Optic Tester, so many to choose from.

Share post

Fiber optic tester choices are varied and many.

A visible fault identifier can be used as a visual inspection tester.

A visible fault identifier is the simplest form of testing.

Firstly confirming the fibers are continuous and secondly that they are connected properly.

A visible fault identifier will locate faults or possible breaks in fibers.

You can also use this in areas of high loss caused by installation problems.

A visible fault identifier can locate breaks in fibers too close to be seen by an OTDR.

In particular, in splice trays or patch panels.

A Microscope can also be used as a visual inspection tester.

A microscope for visual inspection is used all the time.

This inspection method will show the polish finish of a connector as well as any scratches, cracks, dirt or contamination.

We have come a long way with our microscopes as a fiber tester.

Our latest microscope can communicate with and Apple iOS, an Android Smartphone as well as a PC/Laptop (USB.

Making them the safest way to inspect.

It also has pass/fail software to take the guessing out of it.

This eliminates human subjectivity and results in more faster and more accurate results.

Fiber Optic Tester or Fiber Optic Measurement – what is the difference?

A whole different debate is now presented to us.

A test simply checks for the presence of light. Whereas a measurement will tell us the actual amount of light or loss that is present.

That is a huge difference. Just because light is making it to the end of the fiber does not mean the fiber is any good.

Even a partially shattered fiber will pass light and it can be difficult to tell a bad fiber from a good one using this method.

Point made here is, a fiber optic tester alone is not enough when it comes to fibre optic testing.

We need to be able to determine the actual amount of light intensity exiting the fiber.

Fiber Optic Tester in the form of Measurement Equipment.

There are many ways in which we can test fibre optic installations.

These methods will determine the actual amount of optical power or the exact amount of loss in an optical fiber.

OTDR testing or Light Source and Optical Power Meter testing (LSPM) are two well know methods to achieve this.


As a fiber tester, your goal is to establish a network that is fully operational and performing at its best.

While you might consider a “Plugin and hope for the best” approach, there are numerous Fiber Optic Test and measurement solutions available.

Therefore, why take the risk?

Using equipment that has been designed to do the job, will earn you the peace of mind you deserve.
