Huawei Held Highest Worldwide Share; Ciena Leads Outside of China.
The market for DWDM systems significantly grew year-over-year (Y/Y) in the first half of 2019, in part because the comparative period, 1H 2018, includes much lower sales into China caused by the US ban on ZTE. Hence, taking a look at the optical market, excluding China, gives a much better view of the market’s health this period as well as vendor strength.
We estimate that DWDM systems revenue outside of China grew 5 percent Y/Y in 1H 2019. Not surprisingly, when we account for vendor share without China, Huawei, the worldwide market leader, drops considerably below Ciena’s lead share.
In 1H 2019, Ciena held nearly 30 percent share of the optical DWDM market outside of China due to the company’s dominance in North America and growing share in international markets. Ciena’s revenue grew over 20 percent Y/Y. During this period, Huawei held the second-highest share outside of China even though the company’s market share declined slightly from both full-year 2018 and 1H 2018. Nokia continued to hold the third-highest share outside of China with revenue growth in the period exceeding the market average percentage growth of 5 percent.
