Fiber Optic Cable Wall Fixing Method

Proper wall fixing of fiber optic cables involves using a wall mount enclosure or FTTH wall socket, maintaining bend radius, securing cables safely, and testing connectivity to ensure optimal performance.

Choosing the Right Location

Select a dry, accessible wall near power outlets and networking equipment. Avoid areas with high foot traffic, heat sources, or sharp edges that could damage the cable jacket . Ensure the Optical Network Terminal (ONT) is within 3 meters of the wall socket for minimal signal loss .

Wall Mount Fiber Enclosures

A wall mount fiber enclosure protects delicate fiber cables and organizes connections. Choose an enclosure based on the number of cables and future expansion needs. Place it in a secure, easily accessible area, considering temperature and humidity . Small networks may use compact enclosures, while larger setups require more robust boxes.

Installing FTTH Wall Sockets

1. Mark and cut the wall opening (typically 60mm x 40mm) using a template .
2. Secure the back box with screws, ensuring a depth of at least 40mm .
3. Run the incoming fiber cable through the entry port, avoiding sharp bends. Maintain a minimum bend radius of 30mm to prevent signal loss .
4. Prepare the fiber by stripping 30cm of the outer jacket and cleaning the fiber with alcohol .
5. Splice the pigtail to the incoming fiber inside the box using a fusion splicer. Insert the pigtail connector into the adapter and snap the faceplate onto the box .
6. Leave slack (50cm recommended) for future repairs or adjustments .
7. Test light levels using an OTDR or Visual Fault Locator (VFL) to ensure signal integrity, aiming for -27 dBm to -8 dBm for GPON networks .

Running Fiber Cables Internally

Plan the shortest, straightest path from the entry point to the wall socket or enclosure. Use existing conduits or low-voltage pathways when possible. Avoid areas with temperature extremes, high foot traffic, or abrasive surfaces . Keep the workspace clean and well-lit to prevent accidental damage.

Safety and Maintenance

• Wear safety glasses to protect against laser light .
• Cap unused ports to prevent dust contamination .
• Avoid looping or kinking the fiber, as this can degrade performance .
• Ground metallic components if using armored cables . By following these steps, you can securely fix fiber optic cables to walls, protect the delicate fibers, and maintain high-speed, reliable network performance.
