Optical Transport Network (OTN)

OTN (Optical Transport Network) with the recent updates to the ITU-T G.709 standard is quickly becoming the preferred transport technology for telecom operators across many facets of their network. OTN encompasses many enhancements over the traditional SDH or SONET networks such as “optimized transport of legacy and future technologies” and “greater alarming and management of the network”, for these reasons alone it’s the natural progression path for telecom operators. Anritsu is committed to OTN as a technology and has been actively involved with it for many years, please return to this page for future updates and reference material related to OTN.

White Paper 1 - OTN What is it and why is it important?


The first white paper aimed at a basic level explains the background of SDH/SONET and the move towards P-OTS and OTN. This incudes a brief introduction to OTN with overviews of existing technologies and market trends. Includes:

  • Benefits of P-OTS
  • Concerns about about P-OTS
  • The solution
  • Overview of different technologies
