FTTH Installation Guide: Full Deployment Workflow

Fiber to the Home (FTTH) installation requires careful planning and proper technique. This guide covers the complete deployment workflow from planning to activation.

Installation Steps

1. Site survey and path planning. 2. Cable routing from distribution point to subscriber premises. 3. Cable termination at both ends. 4. Fusion splicing of drop cable to pigtail. 5. ONT installation and configuration. 6. Signal testing and verification.

Equipment Needed

Fusion splicer, fiber cleaver, stripping tools, alcohol wipes, splice sleeves, OTDR, power meter, light source, and connector inspection scope.

Best Practices

Maintain minimum bend radius, avoid sharp bends near termination points, label all cables, document splice locations, test every connection, and leave service loops for future maintenance.

Common Mistakes

Insufficient cable slack, poor splice protection, dirty connectors before splicing, incorrect cable stripping length, and failure to test after each splice.
