Dao Anh Thu Student: Vu Manh Tai StudentID: 1221050370 Class: Computer Network Faculty of Information Technology 1 1 Content Optical fiber classification Fiber optics structure The transmission characteristics Advantages and disadvantages 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 Layer core. Layer reflects light back to the core. Layer protection. 4 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. Fiber optics structure 5 The transmission characteristics Adapter: Optical – Electric. Not affected electro-magnetic interference. Dispersion is the phenomenon of light. Used for transmission of long distance. telecommunications systems. 6 The type of fiber optic connector Fiber optic devices convert to copper The transmission characteristics 7 Advantages and disadvantages Advantages Broadband Small size and weight. Low attenuation. Isolated electromagnetic field. The distance between the remote repeater. Reduce the number of iterations, reducing costs. 8 Disadvantages Difficult pairing The use of a photoelectric conversion Advantages and disadvantages 9 Applications Communication environment suitable for implementing network services application integrated with broadband. Transmission distance. Urban Trunk. Local network. 10 Applications 11 The End 12 | Hanoi University of Mining and Geology Learn about fiber optics Instructor: Msc.
