The Optical Transport Network (OTN) defined in ITU G.709, also commonly called “digital wrapper” is a next-generation, industry-standard protocol providing an efficient and globally-accepted way to multiplex services onto optical light paths. It allows network operators to converge networks…

…Transport Network.  It is a standard for optical transport (G.709) developed by the ITU-T standards body, and is sometimes also called a "digital wrapper."  While OTN isn?t necessarily new as a protocol, it is new as a topic in the optical industry for many people. The buzz and conversation…
