Infonetics Research: OTN survey reveals huge shift in carrier plans for optical switching

BOSTON, MA--(Marketwire - May 11, 2011) - Market research firm Infonetics Research today released excerpts from its OTN Deployment Strategies: Global Service Provider Survey, for which carriers in North America, Asia Pacific, EMEA, and CALA were interviewed about their plans for optical transport networks.

"All of the carriers we interviewed for our OTN survey have deployed OTN interfaces in transport applications, and based on conversations aside from this survey, we know very few major carriers in general will 'skip' OTN. There is a huge shift between now and 2014 in the area of optical switching, with the number of carriers with plans to deploy OTN interfaces on electrical switching equipment rising from 37% to 84%," notes Andrew Schmitt, directing analyst for optical at Infonetics Research.


  • 74% of respondent service providers plan to eventually deploy electrical ODU (optical data unit) switching
  • 71% of the carriers interviewed have deployed or will deploy ODU-2/1/0 switching in the core and the metro by the end of 2011
  • By 2014, 40G and 100G ODU switching will each be prevalent in over half of all metro networks
  • The traditional service multiplexing features of OTN are by far the most important in the eyes of carriers
  • 52% of metro optical ports support OTN, but only a fraction are enabled and transmitting using this protocol

For the OTN Deployment Strategies: Global Service Provider Survey, Infonetics interviewed purchase decision-makers with detailed knowledge of their company's OTN transmission and switching equipment about their use and plans for OTN transport. The service providers interviewed represent a significant 23% of worldwide 2010 telecom capex and are a mix of incumbents (52%), competitive operators (32%), and mobile operators (16%) from North America, EMEA, Asia Pacific, and Central and Latin America.

Respondent carriers were asked about preferred equipment used with OTN interfaces; plans for electrical OTN switching in core and metro networks (what level and when); their ratings of various OTN applications (such as service multiplexing onto a single wavelength, ASON/G-MPLS control plane automation, optical private line service delivery, etc.); whether to combine DWDM, OTN switching, and Ethernet/MPLS switching; and more.
