Fibre Optics
Fibre optics is the technology of transmitting information as light pulses through long, thin strands of glass or plastic. It is the backbone of India's high-speed broadband revolution.
Fundamental Concept
It relies on the physical principle of Total Internal Reflection, where light signals are trapped inside a core and travel long distances with minimal loss of intensity.
How does fibre optics work?
- Signal Conversion: Electrical signals (data) are converted into light pulses using a laser or LED.
- Transmission: These light pulses travel through the glass fibre. Because the glass is surrounded by a "cladding" material with a different refractive index, ....
