Optical links are now to be found in short-haul industrial routes, as well as in long-haul telecommunications routes. In order to design and maintain these links, it is important to understand the operation of the individual system components, and this book provides the relevant information.

Inhalt

Part 1 Introduction: historical background; the optical communication link. Part 2 Optical fibres: propagation of light in a dielectric; propagation in a planar dielectric waveguide; propagation in optical fibres; calculation of fibre bandwidth; attenuation in optical fibres; fibre materials and fabrication methods; connectors and couplers. Part 3 Light emission in semiconductors; heterojunction semiconductor light sources; light emitting diodes (LEDs); semiconductor laser diodes (SLDs). Part 4 Photodiodes: photoconduction in semiconductors; PIN photodiodes; long-wavelength PIN photodiodes; avalanche photodiodes (APDs); photodiode noise. Part 5 Introduction to receiver design: fundamentals of noise performance; digital receiver noise; analogue receiver noise; comparison of APD and PIN receivers; measurements and prediction of receiver sensitivity.
