Layer Zero the infrastructure layer

Layer Zero promotes more efficient cooling of network equipment through proper airflow and cable management.

Legrand introduces Layer Zero as a proposed foundation for the OSI model to address the critical role that infrastructure plays in network performance. A new level of stability is introduced to the network by recognizing the importance of the underlying layer and emphasizing best practices in pathway and physical support design. Layer Zero encompasses the entire physical infrastructure that supports your network: not only racks and cabinets with advanced cable management, but underfloor and overhead systems, pathway solutions and more.
