Connecting the optical splitter to the ONU

To connect an optical splitter and ONU, link the OLT to the splitter using fiber, then connect the splitter outputs to ONUs, ensuring proper signal direction, fiber cleanliness, and ONU configuration. Step 1: Prepare Equipment and Check FiberEquipment needed: OLT, ONU, optical splitter (PLC or FBT type), fiber patch cords, and optionally a fiber distribution box (FDB) for organized connections. Inspection: Ensure all fiber end faces are clean and undamaged.

Dirty or scratched connectors can cause signal loss or network failure. Power: Confirm that both the OLT and ONU can power on normally. Step 2: Connect OLT to Optical SplitterUse a single-mode fiber patch cord to connect the PON port of the OLT to the input port of the optical splitter.

The splitter divides the optical signal to multiple outputs, allowing one OLT port to serve multiple ONUs. Typical split ratios are 1: 32 or 1: 64 depending on network design and bandwidth requirements. Step 3: Connect Splitter Outputs to ONUsConnect each output port of the splitter to the PON port of an ONU using fiber patch cords.

Maintain proper polarity: the OLT output should go to the ONU input. If using a fiber distribution box, patch cords can be routed neatly to each ONU location. Step 4: ONU Installation and ConfigurationInstall the ONU at the user premises and connect its LAN, Wi-Fi, or POTS ports to end-user devices.

Bring the ON

U online by sending a serial number request from the OLT.

The OL

T assigns a temporary ID and then a permanent ID after authentication. Verify that the ONU receives optical signals within the normal range and that downstream/upstream communication is functional. Step 5: Testing and VerificationCheck signal strength at each ONU to ensure it is within acceptable limits.

Test connectivity to end-user devices and confirm that bandwidth allocation and services (Internet, VoIP, IPTV) are operational. Document the connections and maintain fiber cleanliness for future maintenance. By following these steps, the optical splitter effectively distributes the OLT signal to multiple ONUs, enabling a reliable FTTH network with proper signal management and user access.
