In a newly released report from the Dell’Oro Group, Wavelength Division Multiplexer (WDM) market revenue is forecast to reach $14 billion by the year 2021. According to the research house, this particular market segment will be driven by the demand for 100G-plus coherent wavelengths. During the period surveyed, the total Optical Transport equipment market, including WDM, multiservice multiplexers and optical switches, is projected to reach $15 billion.
“Demand for coherent wavelengths running at speeds of 100 Gbits/s and higher are expected to grow at a solid pace for the next five years,” said Jimmy Yu, Vice President at Dell’Oro Group. “Specifically, we predict a large ramp in demand for 200 Gbits/s coherent wavelengths, and forecast shipments of these line cards to grow at an 85% compounded annual growth rate.”


Highlights from the Optical Transport 5-Year Forecast Report :include:


  • Demand for WDM metro equipment is forecasted to outpace that of DWDM long haul for the next five years. On an average annual basis, the growth rate for WDM metro revenue will be approximately three-times higher than that of DWDM long haul revenues
  • 100-plus Gbits/s coherent wavelengths will contribute approximately 90% percent of the WDM equipment market revenue by 2021
  • Enterprise direct purchasing for Data Centre Interconnect (DCI) will deeply influence the WDM market. DCI using WDM equipment is forecast to be a $2.4 billion market by 2021.
