Global spending on optical networking (ON) is growing steadily, according to analyst firm Ovum.
The company says that results of $4.08 billion for the second quarter of 2013 were 29 percent higher than they were in the first quarter of the year, and seven percent higher than the second quarter of 2012. Annualised spending grew to $14.9 billion.
Chinese companies led the way. ZTE had its strongest quarter ever, solidifying its position behind Huawei as the second-ranked ON vendor. Annualised spending in Asia-Pacific, at over US$6bn, reached record levels.
