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. This creates an optical virtual private network for each client signal. ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links, able to provide functionality of transport, multiplexing
Recommendation ITU-T G.872 (03/2024) Architecture of the optical
This Recommendation describes the functional architecture of optical transport networks (OTNs) using the modelling methodology described in [ITU-T G.800] and [ITU-T G.805] for the digital layer
Optical Transport Network
It is sometimes also called Optical Transport Hierarchy (OTH). It combines TDM and WDM into a common transport system. The TDM part is hierarchically structured, with Optical Channels (OCh)
How an Optical Transport Network (OTN) Works
The OTN framework acts as a unified transport layer, enabling network operators to simplify operations, improve network visibility, and scale bandwidth efficiently.
