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
Yet another example is an optical module that combines two of the OTUC elements into a 200Gbit/s stream for transmission over the optical channel (wavelength), in which case the method of

G.872 defines an architecture that is composed of the Optical Channel (OCh), Optical Multiplex Section (OMS) and Optical Transmission Section (OTS). It then describes the functionality
The OTU is used in the OTN to support transport via one or more optical channel connections. It also specifies both frame alignment and FEC, as shown in Figure 7.
Learn how OTN layers — ODU, OCh, and WDM — enable efficient optical transport, multiplexing, and wavelength switching in telecom networks.
Explore the intricacies of OTN technology, from its fundamental principles to advanced applications, and learn how it can optimize your optical network.
OTN is often described as the “digital wrapper” for optical networks. It encapsulates diverse client signals — Ethernet, IP, Fibre Channel, SONET/SDH, and storage traffic — into a
