The optical splitter should be connected with its input port to the main fiber line from the network source (such as the ONT or central office), and its output ports to the fibers leading to end users or secondary splitters.

Connection Guidelines

Input Port: The input of the optical splitter must be connected to the main fiber line coming from the network provider or Optical Network Terminal (ONT). This ensures that the incoming optical signal is properly received and ready to be divided among multiple outputs . Output Ports: The output ports of the splitter distribute the optical signal to multiple users or devices. Each output fiber can be connected directly to a user's terminal or to another secondary splitter if cascading is required. When cascading splitters, one output of the primary splitter becomes the input of the secondary splitter . Split Ratio Consideration: Choose a splitter with an appropriate split ratio (e.g., 1:2, 1:4, 1:8) based on the number of users and required signal strength. Higher split ratios divide the signal among more outputs but increase insertion loss, so plan accordingly . Cabling and Connectors: Use compatible fiber patch cables and connectors (SC, LC, or APC types) to connect the splitter. Ensure that all connections are clean and properly seated to minimize signal loss . Signal Testing: After installation, measure the optical power at each output port using an optical power meter to verify that the signal strength is within acceptable limits and that no excessive loss has occurred . By following these guidelines, the optical splitter will efficiently distribute the optical signal to multiple endpoints while maintaining network performance and reliability.
