REDWOOD CITY, Calif. – January 29, 2018 – According to a recent forecast report by Dell’Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, demand for wavelength division multiplexer (WDM) equipment is forecast to drive the Optical Transport market through 2022. 200 Gbps wavelengths are expected to contribute a larger share of capacity shipments over the forecast period.

“We anticipate a number of significant changes to the Optical Transport market over the next five years,” said Jimmy Yu, Vice President at Dell’Oro Group. “Some of these changes include WDM systems increasingly being used in metro access and aggregation locations, disaggregated systems comprising a larger share of the WDM market, issues scaling bandwidth economically, and WDM systems increasingly being purchased directly by end users for data center interconnect (DCI),” continued Yu.

Additional highlights from the Optical Transport 5-Year Forecast Report:

  • The overall Optical Transport market, including WDM, Multiservice Multiplexers and Optical Switches, is projected to grow at a two percent compound annual growth rate over the forecast period.
  • DCI will not be the sole driver behind disaggregated systems taking a large share of the WDM market, as a broader market adoption of disaggregated transponder units will also be a contributing factor.
  • Demand for 100 Gbps wavelengths is expected to peak in terms of revenue in 2018 while shipments are expected to peak in 2020.
