Signal Characterization and Representation

  • Mohammad Azadeh
Chapter
Part of the Optical Networks book series (OPNW)

Fiber optic systems utilize the wide bandwidth of the fiber to transfer very high data rates over long distances. As noted in  Chapter 1, in order to represent information, a physical quantity must be modulated. A “signal” is the representation of information, and a physical signal is realized when a voltage, a current, or an electromagnetic wave is modulated. In fiber optics, we deal with electrical and optical signals. At the level of physical layer, a fiber optic link converts an electrical signal to an optical signal, transmits it over the fiber, and converts it back to an electrical signal at the other side.
