OTN was designed to provide higher throughput (currently 400G) than its predecessor SONET/SDH, which stops at 40 Gbit/s, per channel. ITU-T Recommendation G.709 is commonly called Optical Transport Network (OTN) (also called digital wrapper technology or optical channel wrapper). As of December 2009, OTN has standardized the following line rates.
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 ).
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.

Long-haul Optical Transport Network (OTN) networks were the traditional users of coherent modulation. Cloud scale data centers have become an important consumer of coherent optical modules, particularly in the Ethernet connectivity space for reaches greater than 10 km where the advantages of coherent modulation can outweigh the increased cost.
An optical mesh network is a type of optical telecommunications network employing wired fiber-optic communication or wireless free-space optical communication in a mesh network architecture. Most optical mesh networks use fiber-optic communication and are operated by internet service providers in metropolitan and regional but also national and ...
FlexE is backwards compatible with the existing optical transport network (OTN) infrastructure. A FlexE compatible interface can be connected to a piece of transport gear that is not aware of FlexE. When using it in this manner, FlexE traffic appears to the transport gear as if it was ordinary Ethernet traffic.
Synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) have evolved as the most commonly used protocols for optical networks. The optical transport network (OTN) protocol was developed by the International Telecommunication Union as a successor and allows interoperability across the network as described by Recommendation ...
