ABSTRACT

Advanced fibre cables are used for transmitting high volumes of data in communication systems over long distances for getting very clear images, and in building many sophisticated instruments for a variety of applications. This chapter proposes a few experiments, such as fibre cable end preparation, and the measurements of numerical aperture (NA), power output intensity, and calculations of loss. Fibre Bragg gratings (FBGs) are most commonly used for stabilising pump lasers in optical amplifiers, wavelength division multiplexing, filtering and chromatic dispersion compensation, because their efficiency reduces the cost of optical networking. Non-zero-dispersion fibre type provides optimum performance for optically-amplified systems, over longer distances and with higher capacity. Microstructure fibres can be used to create a supercontinuum (SC). This is a broadening of the narrow laser spectrum into a broad continuous spectrum with many of the properties of coherent light. SCs have applications in frequency metrology and optical coherence tomography.
