REDWOOD CITY, Calif. – July 17, 2017 – In a newly released report by Dell’Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, the wavelength division multiplexer (WDM) market revenue is forecasted to reach $14 B by 2021 driven by the demand for 100+ Gbps coherent wavelengths. During this period, the total Optical Transport equipment market, including WDM, Multiservice Multiplexers and Optical Switches, is projected to reach $15 B.

“Demand for coherent wavelengths running at speeds of 100 Gbps 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 Gbps coherent wavelengths, and forecast shipments of these line cards to grow at an 85 percent compounded annual growth rate,” added Yu.

Highlights from the Optical Transport 5-Year Forecast Report:

  • 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+ Gbps coherent wavelengths will contribute approximately 90 percent of the WDM equipment market revenue by 2021.
  • Enterprise direct purchasing for data center interconnect (DCI) will deeply influence the WDM market. DCI using WDM equipment is forecast to be a $2.4 B market by 2021.
