Current Systems and Future Trends,In previous chapters, we concentrated on the design and performance of individual components for use in optical links. What we have not yet examined is the overall design of practical links, and it is this that initially concerns us here.无法破译 发表于 2025-3-23 21:07:02

Introduction,heory, semiconductor physics, communications theory, signal processing, and electronic design. In a book of this length, we could not hope to cover every one of these different fields in detail. Instead, we will deal with some aspects in-depth, and cover others by more general discussion.

Optical Fibre,rent material, the ., surrounded by a . of similar material. Light waves propagate down the core in a series of plane wavefronts, or .; the simple light ray path used in elementary optics is an example of a mode. For this propagation to occur, the refractive index of the core must be larger than thaVasodilation 发表于 2025-3-24 08:52:26

Photodiodes, link is usually of very low intensity, the detector has to meet a high performance specification: the conversion efficiency must be high at the operating wavelength; the speed of response must be high enough to ensure that signal distortion does not occur; the detection process should introduce theFLOAT 发表于 2025-3-24 18:10:23
Introduction to Receiver Design, further amplification stages, the ., before filtering. An important point to note is that the pre- and post-amplifiers are usually non-saturating. (If the amplifiers did saturate, charge storage in the transistors would tend to limit the maximum detected data-rate.) Because of this, we can use the河流 发表于 2025-3-24 22:16:39
