Coherent 100G set to take over core networks, Infonetics optical survey finds



Boston, MASSACHUSETTS, December 19, 2012—Market research firm Infonetics Research released excerpts from its 40G/100G and ROADM Deployment Strategies: Global Service Provider Survey, which details the plans of operators transitioning optical transmission and switching equipment to higher-speed 40G and 100Gwavelengths.


"The debate between 40G and 100G in WDM networks is over, so for our latest 40G/100G and ROADM deployment strategies survey we focused on identifying how the rollout of 100G will take place and to what degree networks will migrate to coherent technology and ROADMs," explains Andrew Schmitt, principal analyst for optical at Infonetics Research. "What we found is that operators participating in our study expect coherent 100G to take over most core networks by 2015 and even make some minor inroads into the metro, while ROADM."


Among survey respondents, by 2015 coherent wavelengths will account for 68% of deployments in the core and 29% in the metro

100G will rise from just 5% of deployed wavelengths in 2012 to 37% in 2015

Carriers have mixed opinions on the future of various metro 100G approaches, including direct detect 100G, pluggable coherent, and advanced modulations such as 16-QAM

ROADMs are now a major part of optical networks, with ROADM nodes and degree counts set to surge by a factor of more than 2


For its 24-page 40G/100G and ROADM deployment strategies survey, Infonetics interviewed 25 incumbent, competitive, and mobile operators from Europe, North America, Asia, and Latin America about their plans for transitioning to 40G and 100G wavelengths. The study provides insights into reasons for installing 40G and 100G technology, plans for coherent and non coherent detection technology, strategies for deploying 40G and 100G in brownfield and greenfield applications, and ROADM deployment trends.
