REDWOOD CITY, Calif.—February 27, 2019—According to a recently published report from Dell’Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, the optical transport DWDM systems market grew 8 percent in 2018. Ciena, Huawei and Nokia led the market this year.

“Demand for bandwidth continued, unabated for another year, driving DWDM system sales higher for a ninth consecutive year,” said Jimmy Yu, Vice President at Dell’Oro Group. “Most of the growth this year was in DWDM long haul, which grew 13 percent due to network expansion in all of the regions, especially China and North America for telecom infrastructure, subsea capacity and data center interconnect,” added Yu.

Additional highlights from the 4Q 2018 Optical Transport Quarterly Report:

  • Lead manufacturers of optical DWDM systems, ranked in order of revenue share, were Huawei, Ciena, and Nokia with a combined 60 percent share in 2018. The annual revenue growth rate for these top three manufacturers were 11 percent, 17 percent, and 21 percent, respectively.
  • Excluding the Chinese optical market, where a number of manufacturers do not actively sell gear, the lead manufacturer of optical DWDM systems was Ciena, followed by Huawei and Nokia. Ciena’s high share count outside of China is attributed to the company’s strength in subsea capacity and data center interconnect.
