According to the latest report, the DWDM system market in the first half of 2019 saw a significant year-on-year growth. The growth is partly due to a sharp drop in revenue in China in the first half of 2018, when ZTE was hit by a us ban. Therefore, observing the optical market excluding China can better understand the market health and the strength of suppliers during this period.
It is estimated that revenue for DWDM systems excluding China grew by 5% in the first half of 2019 compared with the same period last year. Huawei's share is also significantly lower than Ciena's when excluding suppliers in the Chinese market.
Ciena has nearly 30% of the optical DWDM market outside of China in the first half of 2019, due to its dominance in North America and growing international market share. Ciena's revenue grew more than 20 percent year on year. Huawei, for its part, is second only to Ciena in market share outside China in the first half of this year, although its market share declined compared with the whole of 2018 and the first half of 2018. Nokia, meanwhile, continues to hold its third largest share outside China and its revenue growth is above the market average of 5%.
HTFuture Dense Wavelength Division Multiplexers (DWDMs) are integrated optical modules that combine, or multiplex, and separate, or demultiplex multiple optical signals of different wavelengths in a single fiber. By utilizing proprietary thin film technology in the development and manufacture of our DWDM products, we provide a wide range of solutions for 200 GHz, 100 GHz and 50 GHz ITU wavelength spacing applications. Custom configurations are available upon request.
