Optical Transport Network - OTN

 

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 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.
