By dividing a single optical signal into multiple signals, fiber splitters facilitate the distribution of data from a central office to numerous end-users, maximizing the efficiency of the fiber optic network. This guide demystifies fiber optic splitters. An Optical Splitter, also known as a beam splitter, is a passive optical device that divides a single input optical signal into two or more output signals. Conversely, it can also combine multiple signals into one. It is a crucial component in Passive Optical Networks (PON) and Fiber to the Home (FTTH) deployments. Instead of running separate cables for each user or device, a central piece of equipment—called an Optical Line Terminal (OLT) —sends data down the line to multiple Optical Network Terminals. Where splitters are placed in the network can make significant impacts on fiber counts, network cost and deployment time and operational steps, such as customer onboarding and maintenance. One important note is that splitting architectures should be seen as tools that can be mixed and matched to.
