Optic Cables
Fiber optic cables are replacing aging cooper lines with high-capacity fiber optic cables.
They use light waves to carry information at blinding speeds.
A single fiber optic cable can transmit half a gigabit (500 million bits) per second, replacing 10,000 standard telephone cables.
Data is transmitted more accurately and reliably.
