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, switching, management, supervision and survivability of optical channels carrying client signals ...
ITU-T Recommendation G.709 Interfaces for the Optical Transport Network (OTN) describes a means of communicating data over an optical network. [1] It is a standardized method for transparent transport of services over optical wavelengths in DWDM systems. It is also known as Optical Transport Hierarchy (OTH) standard.
Open Transport Network (OTN) is a flexible private communication network based on fiber optic technology, manufactured by OTN Systems. It is a networking technology used in vast, private networks with a great diversity of communication requirements, such as subway systems, pipelines, the mining industry, tunnels and the like ( ref ).
BT and Ciena Light World's First 800G Super-Channel Demonstrate future-proof nature of BT's UK core optical transport network HANOVER, Md. & LONDON--(BUSINESS WIRE)-- Ciena® Corporation (NAS ...
Optical mesh networks refer to transport networks that are built directly off the mesh-like fiber infrastructure deployed in metropolitan, regional, national, or international (e.g., trans-oceanic) areas by deploying optical transport equipment that is capable of switching traffic (at the wavelength or sub-wavelength level) from an incoming ...

Transport of network management data between the network management system terminal and the SONET/SDH equipment, e.g. using TL1/Q3 protocols. Transport of network management data between SDH/SONET equipment using dedicated embedded data communication channels (DCCs) within the section and line overhead.
The general communication channel (GCC) was defined by G.709 is an in-band side channel used to carry transmission management and signaling information within optical transport network elements. Two types of GCC are available: GCC0 – two bytes within OTUk overhead.
