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.

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.
