Optical networking and fiber-optic cabling systems offer performance characteristics that make them advantageous over copper-based networks and cabling in many environments. Data centers represent one example of where fiber’s bandwidth and distance capabilities often are must-haves. Additionally, the evolution of enterprise networks has pushed fiber farther into the horizontal—in many cases all the way to the end device. This paper explains why fiber-optic cabling’s capabilities position it as the medium of choice for many communications-system requirements in a number of networking environments. It describes the fiber options available to users, the critical role that connectivity plays in the larger picture, and the business justifications for deploying fiber in various network scenarios.
