Chapter 4

Packet Optical Networks and Forward Error Correction


In this chapter, you will learn more about packet optical networks, the latest optical technology used to link nodes in the Illustrated Network. We’ll introduce coherent optical transmission networks and dense wavelength division multiplexing. Then we’ll examine forward error correction (FEC) in depth, starting with simple Hamming codes and working up to Reed–Solomon block codes and new standards used in Optical Transport Networks.

You will learn how to configure FEC codes for various speed links used in the Illustrated Network.
