The optical transport WDM equipment market grew 15% year-over-year in the third quarter, according to a report by Dell'Oro Group.

The majority of the optical transport WDM equipment growth occurred in the Asia Pacific region, according to the report. In the third quarter, coherent wavelength shipments increased 30%.

“The optical market outperformed in the third quarter,” said Jimmy Yu, vice president of Dell’Oro Group, in a prepared statement. “All of the growth was driven by rising demand for coherent wavelengths in metro and long haul WDM systems.  Shipment of 100 Gbps wavelengths continued to rise, but it was a newer, higher speed wavelengths operating at 200 Gbps that truly moved the market revenue higher."
