It is difficult to test splitters by OTDR, especially to test high ratio splitters like 1: 64 or 1:128. Splitter is with high, so OTDR users have to use large pulse width to process the test, because if no large pulse, there will very lower back-scattering signal comes back OTDR for analysis, but once OTDR process testing with large pulse width, its accuracy will be worse. So, HOW to improve the accuracy is an essential issue. Good news is enginners in FirstFiber Technogies Company invested a good method to solve the problem and develop the new splitter OTDR which is good at Splitters testing.

OTDR is a complex Testing Instrument on fiber cable tesing. And prices are much difference. When you select an OTDR, you should know the parameters listed as below,

Launch cable, sometimes is called launch box, fiber reel, or bare fibers. It is acturally a longer fiber jumper, but with much lower insertion loss of both cable and its connectors.

There are two ways to know exactly the loss at a point on an OTDR trace.
In the two-point method, AB two spots are taken at both ends of this point, the closer it is to this point, the better. Finally, the point to be tested is selected to obtain the loss at this point.
In the five-point method, take two points at each end of the test point, through the change of their slope, finally select the point to be tested, you can get the loss at this point.
In fact, the point selected by the OTDR cursor is calculated in this way, which is generally of little practical significance.

8000MAX OTDR

The 8000MAX OTDR is handy, lightweight and rugged enough for any outside plant environment. With a 5.6 inch outdoor-enhanced touchscreen, it delivers an unprecedented user experience, much more convenient and easier operation. The amazing 8-hour battery life will never let a technician down, and the plug-and-play hardware options like fiber inspection probe and USB tools, make every technician’s job easier.
