Optical Transport Network (OTN) - Standards and specifications proposed by the ITU-T. An Optical Transport Network (OTN) is composed of a set of Optical Network Elements connected by optical fibre links. These are able to provide transport, multiplexing, routing, management, supervision and survivability of optical channels carrying client signals. (Also see ITU-T G.709.) www.itu.int
