1. Space Saving: Direct buried optical cables do not occupy ground space, effectively conserving land resources and enabling more flexible urban spatial planning.
2. Easy Maintenance: Compared to overhead lines, direct buried optical cables have lower maintenance costs. Because they are buried underground, they are less susceptible to external factors such as weather and vandalism, resulting in less frequent maintenance.
3. Resistance to External Interference: The underground environment is relatively stable, minimizing external interference for direct buried optical cables, ensuring stable transmission of communication signals.
