Nội dung Text: Đề tài: Learn about fiber optics Optical

Hanoi University of Mining and Faculty ofGeology Technology Information Learn about fiber optics Instructor: Msc. Dao Anh Thu 1
Content 1. Optical fiber classification 2. Fiber optics structure 3. The transmission characteristics 4. Advantages and disadvantages 5. Applications 2
Optical fiber classification • Single-mode ( Ø core 2 - 8 µm). • Multi-mode continuous extraction (Ø core 50 - 125 µm). • Multi-level extraction mode (Ø core > 50 µm). 3
Fiber optics structure • Consists of 3 layers ü Layer core. ü Layer reflects light back to the core. ü Layer protection. 4
Fiber optics structure • The diameter of the core is very little from 5-150 µm. • Light in the optical fiber assembly of the infrared and visible light region. • Core layer made of transparent material, particularly plastic glass. • To pass light in the core layer refractive index of the core layer is greater than the refractive index of the cladding layer. 5
The transmission • Adapter: characteristics Optical – Electric. • Not affected electro-magnetic interference. • Dispersion is the phenomenon of light. • Used for transmission of long distance. telecommunications systems. 6
The transmission characteristics The type of fiber optic Fiber optic devices connector convert to copper 7
Advantages and v disadvantages Advantages • Broadband • Small size and weight. • Low attenuation. • Isolated electromagnetic field. • The distance between the remote repeater. 8 •
Advantages and v disadvantages Disadvantages • Difficult pairing • The use of a photoelectric conversion 9
Applications • Communication environment suitable for implementing network services application integrated with broadband. • Transmission distance. • Urban Trunk. • Local network. 10
