  1. Optical Transport Networks –Services and Standards

  2. Optical Transport Networks –Services and Standards • ITU-T defines Optical Transport Network (OTN) as a set of Optical Network Elements connected by optical fibre links. • Able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of optical channels carrying client signals. • ITU Standard G.709 is commonly called Optical Transport Network (OTN) (also called digital wrapper technology or optical channel wrapper). • OTU0 is currently under development to transport a 1 GbE signal. • OTU1 has a line rate of approximately 2.7 Gbit/s and was designed to transport a SONETOC-48 or synchronous digital hierarchy (SDH) STM-16 signal.

  3. Optical Transport Networks –Services and Standards • OTU2 has a line rate of approximately 10.7 Gbit/s and was designed to transport an OC-192, STM-64 or 10Gbit/s WAN. • OTU3 has a line rate of approximately 43 Gbit/s and was designed to transport an OC-768 or STM-256 signal. • OTU4 has a line rate of approximately 112 Gbit/s and was designed to transport a 100 Gigabit Ethernet signal • ITU-T Study Group 15: Optical transport networks and access network infrastructures • ITU-T G.872: Architecture of optical transport networks

  4. Optical Transport Networks –Services and Standards • ITU-T G.664: Optical safety procedures and requirements for optical transport systems • ITU-T G.692: Optical interfaces for multichannel systems with optical amplifiers • ITU-T G.709: Interfaces for the Optical Transport Network (OTN) • ITU-T G.798: Characteristics of optical transport network hierarchy equipment functional blocks • ITU-T G.871: Framework for optical transport network recommendations • ITU-T G.874: Management aspects of the optical transport network element • ITU-T G.959.1: Optical transport network physical layer interfaces
