Transmission via optical transport network
An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. It encapsulates diverse client signals — Ethernet, IP, Fibre Channel, SONET/SDH, and storage traffic — into a standardized format, enabling transparent transport, advanced management, and carrier-grade. That sounds straightforward enough, but the real value comes from how the system manages speed, reach, routing, and resilience all at.
