G.709 The Optical Transport Network (OTN)
In short, OTNs will apply the operations, administration, maintenance, and provisioning (OAM&P) functionality of SONET/SDH to DWDM optical networks. The OTN is specified in the International
Building operator-centric digital twins for optical transport networks
Abstract The complexity and heterogeneity of modern optical transport networks (OTNs) demand advanced solutions to enhance their operation and maintenance.
Chapter5 The Optical Transport Network
The OTN structure, in addition to the physical media layer network that defines the optical fiber type, consists of three layers—the optical channel, the optical multiplex section, and the optical
