REDWOOD CITY, Calif. – July 16, 2015 –In a newly released Optical Transport forecast report by Dell’Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, wavelength division multiplexer (WDM) equipment demand is expected to drive the Optical Transport market to $15 billion by 2019.

“The network still needs a lot of raw bandwidth and WDM is the best equipment to deliver that,” said Jimmy Yu, Vice President of Optical Transport Market Research at Dell’Oro Group. “While high demand for long haul equipment will continue, the biggest growth that we are projecting is in metro applications. The majority of metro equipment purchases will still be made by telecom service providers, expanding their metro network capacity for higher speed services, but we also see a strong trend towards enterprises such as Internet content providers and financial institutions procuring and installing their own high speed 100 Gbps links. This trend is being powered by the increasing importance of data centers to a company’s core business,” added Mr. Yu.

Select information from the recently published Optical Transport forecast report:

  • WDM Metro revenue is forecast to grow at a 10 percent compounded annual growth rate (CAGR)
  • Over 75 percent of WDM network capacity installed across the next five years will be from 100 Gbps wavelengths
  • Demand for 200 Gbps wavelengths is expected to ramp in metro applications this year and is forecast to contribute nearly 25 percent of WDM Metro equipment revenue by 2019.
