Exam Bank Questions and Answers for Optical Fibre Transmission Characteristics Already Passed

Optical Fibre - Answers Dielectric waveguide structure guiding light using core, cladding, and buffer.

Refractive Index Profile - Answers Variation of refractive index across the core, cladding, and buffer of an
optical fibre.

Wavelengths - Answers Infrared wavelengths (820 nm, 1300 nm, 1550 nm) used in telecommunications
via optical fibres.

Preform - Answers Thick glass rod melted to form optical fibre, with core and cladding dimensions.

Core Diameter - Answers Typically 10 µm for single mode and 62.5 µm for multi mode fibres.

Cladding Diameter - Answers 125 µm diameter for both single mode and multi mode fibres.

Ray Picture - Answers Intuitive representation of light propagation in optical fibres using vectors.

Meridional Rays - Answers Simplified description considering rays passing through the centre of the fibre
core.

Wavefronts - Answers Surfaces of constant phase separated by 2π radians, perpendicular to rays.

Phase Velocity - Answers Velocity at which wavefronts propagate along a waveguide.

Diffraction - Answers Effect ignored in ray approximation, significant in waveguides with dimensions
comparable to wavelength.

Snell's Law - Answers Law governing reflection and transmission at core-cladding interface in optical
fibres.

Critical Angle - Answers Angle of incidence leading to total internal reflection in optical fibres.

Numerical Aperture - Answers Property indicating light-gathering ability of an optical fibre.

Relative Difference - Answers Difference in refractive indices of core and cladding, expressed as a
relative value.

Profile Parameter - Answers Relative difference in refractive indices, denoted by the parameter D.

Max Launch Angle - Answers Maximum angle at which light can be launched into a fibre and guided.

Propagation Constant - Answers Component of wave number along the z-axis in optical fibres.

Modes - Answers Sets of wavefronts representing the motion of light in optical fibres.

Standing Waves - Answers Wavefront interference patterns forming allowed standing wave patterns.

Wave Number - Answers Number representing the spatial frequency of the wave in optical fibres.
