Fiber optic splitter and switch are devices used to build networks, and they can be connected by fiber optic cable. Typically, fiber optic PLC splitter are used to split an optical signal into multiple outputs that can be connected to different devices or end nodes. The switch can connect various devices together and realize the communication between these devices by exchanging data packets. Therefore, connecting fiber optic PLC splitters to switches can help build a more flexible and efficient network system.
