An optical cable, often referred to as fiber optic cable, is a type of cable that uses light to transmit data. It is made up of thin strands of glass or plastic fibers that carry light signals. These cables are designed to transmit information over long distances at high speeds, much faster than traditional electrical cables like copper wires.
Here’s how it works:
Optical cables are commonly used for internet connections, phone lines, and network connections because of their ability to handle large amounts of data quickly and efficiently.
Here’s how it works:
- Light signals: Instead of sending electrical signals, optical cables send data in the form of light. This is done using lasers or LEDs (light-emitting diodes) that turn electrical signals into light, which then travels through the fibers.
- Fiber structure: Each optical fiber consists of a core, where the light travels, and a cladding, which reflects the light back into the core, ensuring it stays on the right path without leaking out.
- Advantages: Optical cables are faster, more reliable, and immune to electromagnetic interference (which can affect copper cables). They can carry more data over longer distances without degrading the signal.
