A fiber optic coupler splits or combines light signals in optical networks, improving data flow, reliability, and network flexibility for various applications. 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. For every 2X increase in split ratio, power is reduced by roughly 3 dB. Know the difference between passive and active. The innovation of Passive Optical Networking, allows us to use these splitters when designing flexible and expandable network topologies, creating fault-tolerant networks, and making efficient use of fiber.
