How to test a plug-in type optical splitter
Attach a launch reference cable to the test source of the proper wavelength (some splitters are wavelength dependent), calibrate the output of the launch cable with the meter to set the 0dB reference, attach to the source launch to the splitter, attach a receive launch. Attach a launch reference cable to the test source of the proper wavelength (some splitters are wavelength dependent), calibrate the output of the launch cable with the meter to set the 0dB reference, attach to the source launch to the splitter, attach a receive launch. Testing a splitter or other passive fiber optic devices like switches is little different from testing a patchcord or cable plant using the two industry standard tests, OFSTP-14 for double-ended loss (connectors on both ends) or FOTP-171 for single-ended testing. First we should define what these. Although both optical splitters and patch cords are tested using an optical power meter and light source, there are some differences in testing them.

How to accurately test the quality of pigtail fibers
Technical testing provides the most accurate method to evaluate a fiber pigtail. These tools reveal defects that visual inspection cannot detect. There are two reasons we may want to test bare fiber, by that we mean fiber that has not been terminated in connectors but is simply plain optical fiber, The first one is to ensure the fiber or cable being manufactured meets its specifications, as is done by every manufacturer. The second reason is. The Contractor tasked to perform testing or splicing on any fiber optic cable will follow these testing standards to fulfill their contractual obligations.
