Physical considerations drive how the longest, most exposed links are designed and protected. The campus and WAN backbone cabling and infrastructure must span between buildings and across floors, so it encounters a wide range of environments, distances, and physical stresses. It needs robust pathways, appropriate conduits, fire-rated spaces, proper bend radii, pull tensions, climate control, moisture protection, and seismic or movement considerations. If these backbone runs aren’t designed and protected for those realities, the impact is global—the backbone supports all higher-level connections, so failures or inefficiencies here ripple through the entire network. Horizontal copper cabling, patch panels, and end devices are important too, but they run shorter distances in more controlled environments, so they’re less subjected to the broad physical factors that affect the backbone.
