🔦 Optical Fiber Technology

📖 What is Optical Fiber?

Optical Fiber என்பது Glass அல்லது Plastic Core மூலம் Light Signal-ஐ பயன்படுத்தி Data அனுப்பும் Transmission Medium ஆகும்.

🎯 Why Optical Fiber?

✔ Very High Bandwidth

✔ Long Distance Communication

✔ Low Signal Loss

✔ EMI Free Transmission

✔ High Reliability

⚙ How Optical Fiber Works?

Transmitter-ல் Electrical Signal Light Signal ஆக மாற்றப்படுகிறது.

Light Fiber வழியாக பயணித்து Receiver-ல் மீண்டும் Electrical Signal ஆக மாற்றப்படுகிறது.
