How does fiber-optic cabling compare to UTP cabling?
Fiber beats UTP on bandwidth, distance, and immunity to EMI/electrical hazards; UTP wins on cost, installation simplicity, and safety. That's why fiber is reserved for backbones and long point-to-point links.
* Fiber wins on bandwidth, distance, and EMI immunity; UTP wins on cost and install simplicity — so fiber is reserved for backbones and long links. *
| Implementation Issue | UTP Cabling | Fiber-Optic Cabling |
|---|---|---|
| Bandwidth | 10 Mb/s - 10 Gb/s | 10 Mb/s - 100 Gb/s |
| Distance | Relatively short (1-100 meters) | Relatively long (1-100,000 meters) |
| Immunity to EMI/RFI | Low | High (completely immune) |
| Immunity to electrical hazards | Low | High (completely immune) |
| Media and connector costs | Lowest | Highest |
| Installation skills required | Lowest | Highest |
| Safety precautions | Lowest | Highest (laser safety) |
