How does ultra fast broadband work?
What is the difference between broadband and fiber?
The difference between broadband and fiber resides in the underlying technology. Traditional broadband networks send data signals in the form of electrical pulses through copper cables, while fiber optic cables are made of glass and transmit data signals in the form of light pulses sent by laser. Fiber optic cables don't conduct electricity, so there are no issues with ground loops or lightning strikes.
On a practical level, there are several differences.
- Network availability. Broadband networks are everywhere, whereas optical fiber networks may not be available for every office, factory or home – especially if these are located in a remote or rural location.
- Reliability and capacity. Fiber networks are more reliable, since they are not affected by electrical disturbance, and do not get overloaded with traffic during peak hours like broadband networks do.
- Speed. An optical fiber network’s speed is far superior to broadband. Moreover, when traffic on a broadband network increases, speeds will slow down during peak periods.
- Cost. While installation costs have come down for optical fiber networks, they still cost more than traditional broadband.
