How to test the directionality of an optical splitter

These components can be tested using a RF signal source, termination resistors, and the Frequency Selective Voltmeter. NOTE: Be sure to consult the manufacturers data sheet to obtain the parameters for the specific device you are testing. 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. Calculating splitter loss in optical fibers is essential for designing efficient optical networks. These are known as passive optical splitters, and they perform the function of splitting the light signal without using any power. Splitters are essential when you want one fiber line from a central office (like an ISP's headend or data center) to serve multiple homes or businesses.
