Optical Fibre,n range from 5 to 75 μm and can be made from glass or plastic or a combination of the two. Optical fibre can be found in very-high-speed (40 Gbit/s), long-haul (>100 km) routes that carry data from telephones, computers and Internet search engines. In this chapter we shall examine the properties and

Optical Transmitters,erates the light. This chapter is concerned with the generation of light from LEDs and lasers. It begins with some semiconductor physics before going on to examine light generation from a variety of sources. Fibre lasers are also discussed.

Introduction to Receiver Design, voltage prior to low noise preamplification; a post amplifier provides amplification; a filter restricts the system bandwidth; a detector restores the original signal. Most optical links use direct detection – the optical receiver (the photodiode) directly demodulates the light. This is different t

Preamplifier Design,signal without major distortion (for digital it was 0.5B). In this chapter we will examine the electronic circuits used to amplify the signals at the end of a link. We will discuss the bandwidth limitations and the noise performance of several designs and study how to design the preamplifiers.
