Fiber is delivered via optical fiber cables (OFC), which transmit data using light signals. Here's a more detailed explanation:
Fiber Optic Delivery: How it Works
Unlike traditional copper wires that use electricity to carry data, fiber optic cables use light pulses. These cables are made of incredibly thin strands of pure glass, often as thin as a human hair, that act as conduits for light signals.
The Process:
- Data Encoding: Information is first encoded into light signals. This is done by modulating the light, which means changing its intensity or other properties to represent bits of data.
- Transmission: These light signals travel through the hair-like glass fibers within the optical cable.
- Reception: At the destination, the light signals are decoded back into the original data.
Key Advantages Over Copper:
- Speed and Capacity: Fiber optic cables offer much higher bandwidth and faster speeds compared to copper wires. This is because light can travel faster and carry much more data than electricity. According to the provided reference, this speed and capacity are maintained even during peak usage times.
- Reduced Signal Loss: Unlike copper wires that suffer from signal degradation over longer distances, fiber cables experience minimal signal loss due to the efficient transmission of light.
- Immunity to Interference: Fiber cables are not susceptible to electrical or radio interference, which ensures reliable and consistent data transmission.
Practical Implications:
- Reliable Internet: Fiber optic cables are essential for providing high-speed and reliable internet, especially as bandwidth needs increase.
- Improved Streaming: The higher capacity of fiber enables smooth streaming of high-definition video content without buffering.
- Future-Proof Infrastructure: As data demand continues to grow, fiber offers the best solution for scalable and future-proof infrastructure.
| Feature | Copper Wire | Fiber Optic Cable |
