Is the testing technology for optical splitters difficult

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. What are Optical Splitters? The fiber optic splitter is a device used in fiber optic networks to divide a single optical signal into multiple signals. its challenges when testing or troubleshoo 2 splitter can have as much as 15-17db of loss. Because of this, you'll need a PON specific OTDR tester with high dynamic range, high resolution and sophisticated software to p operly identify and test through the splitters. Brief Introduction to.
