Optical Transport Network - OTN

NEW - MT1100A and MT1000A - Redefining Network Testing

MT1100A Network Master Flex

All-in-one testers with OTN mapping - the NEW MT1100A Network Master Flex and MT1000A Network Master Pro redefine the direction of future test platforms by bringing all your network test requirements to a portable device.

These instruments support OTN, MPLS-TP, Ethernet and Fibre Channel, as well as legacy networks, including PDH/DSn and SDH/SONET.

With up to 100 Gbps per port on the MT1100A Network Master Flex, these products are ideal for field installation and maintenance, as well as R&D and manufacturing tests.

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.



OTN Reference Poster

The A1 size or format OTN reference poster provides all the data required by the next generation of fixed line (OTN) engineers in a single location. The comprehensive data provided by this poster will allow any engineer to quickly understand the many facets of OTN.

Key details include:

  • OTU Frame diagram
  • Detailed explanation of the all section of the OTU Frame
  • Interface rates broken-down to payload rates including example payloads
  • Mapping structure
  • Maintenance Signal Network Interaction
  • TCMi operation details
  • Understanding accurate BER Testing via the ITU-T O.182 standard (see below whitepaper for more details)
  • Complete glossary of acronyms and payload descriptions



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

White Paper 2 - OTN What is it and How does it Work?


Aimed at the Engineer level this 16 page white paper follows on from the first white paper to provide more in depth information including a detailed OTN technology overview. Detailing OTU, ODU, OPU and FEC this paper also explains Mapping and provides an overview of the recent improvements in transmission technologies.

  • Technology overview
  • The OTN frame
  • Mapping
  • Benefits of OTN

White Paper 3 - OTN The Deep Dive into the Details that Make it Tick?


Written for an Engineer with a focus on OTN or wishing to gain a greater understanding of how an OTN works. This paper continues deeper into OTN from the first two offering details on some of the more technical OTN functions. Looking into the bits which make up the OTN frame and what they do, areas discussed includes:

  • BEI, BDI and IAE (error indications)
  • TCM layers
  • FTFL (fault indicators)
  • APS/PCC (protection)
  • AMP, BMP and GMP (mapping types)
  • FEC and super FEC
  • Maintenance signals interaction
