Sales of DWDM systems grew 8% in 2018, according to a new report from Dell'Oro Group. Huawei, Ciena, and Nokia ascended to the top market share spots for the year; the three accounted for 60% of DWDM systems sales, says the market research firm.
"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% 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.
Each of the top three systems vendors saw their DWDM revenues grow by double digits, the report states. Huawei’s sales were up 11%, Ciena’s 17%, and Nokia’s jumped 21%. Excluding sales to China, Ciena becomes the market share leader, thanks in large part to its strength in the submarine network and data center interconnect niches.
Dell'Oro Group released its year-end figures in its latest “Optical Transport Quarterly Report.” The report covers the optical network systems market via tables covering manufacturers' revenue, average selling prices, and unit shipments (by speed including 100 Gbps, 200 Gbps, and 400 Gbps). The report tracks DWDM long-haul terrestrial, WDM metro, multiservice multiplexers (SONET/SDH), optical switch, optical packet platforms, and data center interconnect (metro and long haul).
