How Fiber Internet Works

Fiber uses pulses of light (photons) traveling through glass threads thinner than a human hair.

Speed of light in fiber: ~200,000 km/s. Electromagnetic waves in copper cable: ~230,000 km/s. Nearly equal.

The difference: fiber carries FAR more data per second (terabits) because light pulses don't interfere with each other.

No interference from electrical appliances. No degradation over distance (within 70km). No shared copper with neighbors.

FTTH (Fiber to the Home) = fiber all the way. FTTN = fiber to node, then copper to your house = slower.

Result: symmetrical upload/download, <10ms ping, no peak-hour congestion. Copper simply cannot match this.
