The Magic Behind Optical WAN Networking: OSI's Layer 2

We'll look at SONET/SDH and its equipment, OTN Optical Transport Network, and its technology and equipment. We'll cover WDM wavelength division multiplexing, its two versions CWDM and DWDM, and compare SONET and OTN. Understanding Data Link Services, WAN technologies over time, Enterprise-Carrier-IPS at Layer 2, self-healing fiber links, and more.

We'll review DOCSIS and how cable operators deliver ethernet via RF and peek at DSL and its technology. Ethernet in the WAN, take a look!
