Fiber-Optic Communication

Fiber-Optic Communication

Fiber-optic communication is a modern method of transmitting data, voice, and video signals using light pulses through optical fibers. Instead of relying on electrical signals in copper wires, fiber-optic cables use thin strands of glass or plastic fibers to carry information at the speed of light.

This technology enables high-speed, long-distance, and large-capacity data transmission, making it the backbone of the internet, telecommunications, cable TV, and data networks.

Fiber-optic communication works by:

1. Converting electrical signals into light signals using a laser or LED transmitter.

2. Transmitting light signals through optical fibers with minimal loss.

3. Converting light signals back into electrical signals at the receiver’s end.
