Choosing fiber optic cable types for a commercial building starts with the link you need to support: its route length, required network speed, switch optics, and installation environment. An MDF-to-IDF backbone, warehouse expansion, and building-to-building connection may need different cable constructions even when they use the same fiber type.

Underground fiber optic installation connects commercial buildings, network rooms, and campus facilities through a planned outside route. The cable is only part of the project. Pathway condition, utility coordination, building entrances, excavation access, restoration, and testing all affect the final scope.

Fiber optics lines are strands of glass that are as thin as the human hair. They carry digital information over long distances at great speeds. Fiber optics are also used in medical imaging devices and mechanical engineering inspections.

Internet usage has evolved over the last decade or so.
