Part II. Ethernet Media Systems
This part will describe the Ethernet media systems. We begin with the basics of Ethernet media signaling in Chapter 7, where we also cover the Energy Efficient Ethernet system, which saves power by modifying the media signaling during idle periods.
Chapters 8 through 14 describe specific media systems. Each of the media system chapters covers the media components used for a given speed of Ethernet. The format of each chapter is identical, which helps to organize and clearly present the information. While an effort was made to avoid needless duplication of text, the format leads to some unavoidable repetition in these chapters. This is especially noticeable if you read several media chapters in a row.
