The text provides a comprehensive overview of the functional architecture of Optical Transport Networks (OTNs) as defined by ITU-T Recommendations. OTNs are designed to transport, aggregate, route, supervise, and ensure survivability for digital clients across optical media. COMPARISON OF SDH AND OTN 1 Abbreviations 2 What is OTN/OTH 2. 2 Full. ITU-T recommendation G. 709, Interface for the optical transport network (OTN), is among the latest of these standards, and its aim is to address the transmission requirements of today's wide range of services; namely, it was developed to assist in network evolution to higher bandwidth and improve. The Optical Transport Network (OTN) is an internationally standardized set of protocols that define how digital signals are encapsulated, multiplexed, and transported across optical fiber infrastructure. Key elements of OTN include: Standardized framing (the “digital wrapper”): OTN adds overhead. In short, OTNs will apply the operations, administration, maintenance, and provisioning (OAM&P) functionality of SONET/SDH to DWDM optical networks. 709 Network Node Interface for the OTN.
