Fiber

• Characteristic
  • Light is an electromagnetic wave
  • Refraction, reflection, and total reflection of light
• Classification
  • Silica Fiber
    • Cable TV and Communication System
  • Fluorine Doped Fiber
    • Doping of cladding
  • Infrared Optical Fiber
    • Light energy transmission
  • Compound Fiber
    • Fiber optic endoscopes for medical services
  • Plastic Clad Fiber
    • Local area network and close range communication
• Advantages
  • bandwidth
  • Low loss
    • Same loss across all cable TV channels
    • Loss hardly changes with temperature
  • Strong anti-interference ability
    • Small diameter, light weight, and convenient installation
  • High fidelity
    • not easily eavesdropped, thus facilitating confidentiality
  • Reliable working performance
    • A small number of equipment naturally leads to high reliability
  • Costs continue to decline
    • The source is very rich, and the cost will be further reduced
• Construction methods
  • Hot melt welding method
    • Use the high-voltage arc of the fiber optic fusion splicer to melt and connect two optical fibers
  • Cold welding method
    • Use fiber optic cold connectors to connect fibers or connect fibers to optical communication equipment
