How to connect the fiber optic panel cable to the optical splitter

To connect a fiber optic panel to an optical splitter, identify the input/output ports, prepare and clean the fibers, splice or connectorize them, and secure the connections while testing signal quality.

Step 1: Identify Splitter Ports

• Input Port: Usually marked as "IN" or "E"; this is where the main fiber from the network provider is connected .
• Output Ports: Multiple ports labeled for distribution to end devices. For some splitters, like Huawei FTTR, the green port is a cascade port, not the uplink .
• Splitter Type: Choose PLC for uniform splitting or FBT for non-uniform splitting, depending on your network requirements .

Step 2: Prepare the Fiber

• Strip the Jacket: Use a fiber stripper to remove about 5mm of the protective jacket from the fiber .
• Clean the Fiber: Wipe the bare fiber with alcohol or a cleaning pen to remove dust and debris .
• Cut Evenly: Ensure the fiber end is smooth and straight to prevent signal loss .

Step 3: Splicing or Connectorization

• Fusion Splicing: Align the fiber cores in a fusion splicer and fuse them together. Protect the splice with a splice protector .
• Mechanical Splicing: Insert fibers into a mechanical splice connector and secure according to the manufacturer's instructions .
• Connector Connection: Plug the prepared fiber into the splitter's input and output ports, ensuring no tension on the fibers .

Step 4: Mounting and Securing

• Placement: Install the splitter flat or wall-mounted with connectors facing downward to prevent dust accumulation .
• Bend Radius: Maintain a fiber bend radius greater than 5cm to avoid damage .
• Secure Connections: Use clips or screws to hold connectors in place and prevent loosening .

Step 5: Testing and Verification

• Optical Power Measurement: Use an optical power meter to check input and output power. Ensure insertion loss is within the theoretical range (e.g., ~3.5dB for a 1:2 split), .
• Signal Stability: Verify that each output channel's optical power is within -20dBm to -25dBm to avoid network issues .
• Troubleshooting: If the signal is unstable, check for cleanliness, correct port orientation, and secure connections .

Additional Considerations

• Carrier Support: Confirm that your service provider allows splitting if done at home .
• Multi-Level Splitting: For FTTR systems, up to four levels of cascading are supported, but ensure optical power does not fall below critical thresholds .
• Indoor vs Outdoor: Use IP20-rated enclosures for indoor and IP65/IP66-rated for outdoor installations . Following these steps ensures a reliable, low-loss connection between your fiber optic panel and optical splitter, supporting stable network performance and long-term reliability.
