Correct Installation Method for Optical Splitter

Installing an optical splitter involves careful preparation, proper placement, precise fiber handling, and post-installation testing to ensure minimal signal loss and reliable network performance.

Preparation and Tools

Before installation, gather the necessary tools and materials: fiber optic cables, connectors, a fiber optic splitter (PLC or FBT type), fiber cleaver, wire stripper, cleaning supplies (alcohol wipes or cleaning pen), optical power meter, and a fusion splicer or mechanical splice kit if splicing is required . Determine the splitter type, split ratio, and wavelength compatibility (e.g., 1310nm/1550nm) based on your network requirements .

Placement

Optical splitters can be installed indoors or outdoors depending on network design. Indoor locations include central computer rooms, building wiring closets, or floor wiring boxes, while outdoor splitters may be housed in weatherproof enclosures . The splitter should be mounted flat or on a wall with the connector facing downward to prevent dust accumulation . Ensure the installation area is dust- and moisture-proof, and maintain a fiber bend radius greater than 5 cm to avoid damage .

Fiber Preparation and Connection

1. Measure and Cut: Cut fiber optic cables to the required length using a fiber cleaver or wire stripper .
2. Strip the Jacket: Carefully remove the protective jacket to expose the inner fibers .
3. Clean the Fibers: Use a fiber optic cleaning kit to remove dust or debris from fiber ends and adapter holes .
4. Identify Ports: Determine the input and output ports on the splitter; the input port usually has a single fiber, while output ports have multiple fibers .
5. Splice or Connect: Align the fiber core with the splitter port and secure it using a fusion splicer, mechanical splice, or connector adapter. Coil any excess fiber neatly to prevent stress .

Securing and Testing

After connecting the fibers, secure the splitter and connectors using clips, screws, or protective slots in a fiber distribution box or terminal box . Test the installation using an optical power meter to measure input and output power. Ensure the insertion loss is within the nominal splitter loss (e.g., 1:8 PLC splitter standard loss ≈ 10.7 dB) and check uniformity between output ports (loss variation <1 dB for 1×16 PLC splitter), . Troubleshoot any excessive attenuation to ensure smooth fiber link operation.

Additional Tips

• Use PLC splitters for uniform splitting and FBT splitters for non-uniform splitting .
• Avoid placing splitters in areas with high dust or moisture exposure.
• Always maintain proper bend radius and avoid sharp bends to prevent fiber damage .
• For FTTH networks, splitters are typically installed in fiber access terminals, wall-mount termination boxes, or fiber splice enclosures . Following these steps ensures a reliable optical splitter installation with minimal signal loss and optimal network performance.
