Professional Answer: Common challenges in fiber optic installation include improper cable handling (e.g., exceeding the minimum bend radius), poor cable termination leading to signal loss, and damage from environmental factors. To prevent these issues, it is crucial to use high-quality, durable equipment and follow best practices. This includes using proper pulling or blowing equipment to avoid excessive tension, ensuring cable ends are clean and polished before splicing, and selecting armored cables for direct burial applications.
