DWDM market reach $16billion in 2023 by Dell'oro


"The 100Gbps growth cycle is over, but that doesn't mean 100Gbps wavelength coherence is no longer needed," said Jimmy Yu, group vice-president at Dell 'oro. However, there is a good reason to choose the 200+Gbps wavelength. Simply by using the new 60Gbaud and upcoming 90Gbaud line CARDS, the coverage of 200Gbps and 400Gbps coherent signals can be further extended to help service providers reduce the cost per bit. Therefore, we expect 100Gbps shipments to decline over the next five years, while 200+Gbps shipments will grow at a compound annual rate of 50%."
 
 
 
The report also predicts that the entire WDM market, including metropolitan and long-distance systems, will grow at a compound annual rate of 5 percent. In the forecast period, the growth rate of WDM metropolitan area will be slightly faster than DWDM long-distance. In addition, the breakdown of the WDM system segment is expected to exceed $3 billion by 2023. Within three years, 200Gbps wavelength will occupy the largest share of shipments; 800Gbps wavelength shipments will start to increase from 2020.
