Data Flow in Optical Transport Networks
Basically, OTN defines a digital wrapper that wraps client signals into Optical Data Units (ODUs) before they are sent through optical channels. This creates an optical virtual private network for each client signal. The objective is to provide the telecommunications engineers with a document that forms the basis for understanding OTN. The diagram I've shared, titled “How OTN Maps the Client Payload”, visually. OTU4 stands for Optical Transport Unit 4. Raw. Cisco Optical Networking are well suited for a lot of situations like long distance dwdm We build solutions for customers (primarily the DOD) to use at the edge.
