Where do outside plant (OSP) cables typically enter a building?

Outside plant (OSP) cables typically enter a building at the entrance facility. This area serves as the point at which outside communication connections, such as telecommunication and data services, transition from the external environment into the internal infrastructure of a building. The entrance facility is designed to accommodate the necessary equipment, protection, and pathways for these OSP cables, ensuring effective management and distribution of services throughout the building.

This location minimizes the risk of damage to the cables, facilitates proper grounding and bonding, and allows for the installation of necessary termination equipment such as splice trays or patch panels. It is specifically engineered to handle the integration of outside services, making it the designated entry point for OSP cables, while ensuring compliance with safety and code requirements.
