10. Fiber Manufacturing
• Slight Fluctuation in mixing of Ingredients.
• Impossible to eliminate.
• Slight changes in density of Silica cools and
Solidifies.
17. Non Linear Scattering losses
• Depends on Optical Power Density
• Power Transfer in Forward or Backward
directions depends on frequency.
• Threshold power level High Frequency
34. Core and Cladding Loss
• Different Material (elements), Density,
Composition.
• Different Attenuation co-efficient (α1 & α2).
• Lower order vs Higher Order
39. Distortion Loss
• Inter Modal Dispersion (Multi Mode)
• Intra Modal Dispersion (Single Mode)
• Group Velocity Dispersion
• Chromatic Dispersion
High energy speed of light in different modes
41. Types of Intra Modal Dispersion
• Material Dispersion (Variation of RI of Core)
• Wavelength Dispersion (SM fiber 80% power in
core & 20% power in cladding)
• LED 1550nm SM
• MM different velocity waves
