Fiber optics generally refers to the technology that allows the transmission of voice, video, and data through a glass wire. Fiber optic wire carries much more information than conventional copper wire and is far less subject to electromagnetic interference and because of that it is better suited for video streams and large data transfer that the more common copper lines.
Transmission on fiber optic wire requires repeating at distance intervals, and the glass fiber requires more protection within an outer cable than traditional copper to keep it from breaking. Still, fiber optics is the best quality solution for campus environments and for extending reach beyond the limitations of shielded copper cable
