A cable splitter itself does not directly affect internet speed. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. At its core, an FBT splitter is a passive optical device that takes a single optical input signal and divides it into two or more output signals. The manufacturing process involves fusing two or more optical fibers together by applying heat. Optical splitters are passive devices that allow a single fiber optic line to be divided into multiple lines, enabling the distribution of the same high-speed connection to various endpoints. It is a crucial component in Passive Optical Networks (PON) and Fiber to the Home (FTTH) deployments.
