Which class of telecom infrastructure addresses multiple buildings at a single site?

The correct answer is Class 3. This class of telecommunication infrastructure is designed specifically to connect multiple buildings within a single site. Class 3 systems enable communication and data transfer between different structures, making it ideal for environments like corporate campuses, educational institutions, or industrial sites that need extensive interconnectivity.

Each class of telecom infrastructure has specific applications:

• Class 1 generally pertains to very large building complexes or urban centers linked over distances, which might not focus as much on intra-site connectivity.

• Class 2 primarily focuses on a single building structure, emphasizing the internal communication needs rather than inter-building communication.

• Class 4 typically deals with very large and complex environments and may include connectivity that spans across multiple sites rather than focusing solely on buildings within a single location.

Class 3's emphasis on servicing multiple buildings at the same site differentiates it from the other classes, highlighting its suitability for facilitating extensive network systems in those particular scenarios.
