Components of an optical transport network

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, switching, management, supervision and survivability of optical channels carrying client signals. This creates an optical virtual private network for each client signal. It ensures data integrity, manages bandwidth allocation, and simplifies. 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 standardized format, enabling transparent transport, advanced management, and carrier-grade reliability. The diagram titled “The multiple layers of the OTN network” clearly illustrates how the various layers within the OTN framework work together to ensure smooth transport of different client signals.
