The Wavelength Division Multiplexer (WDM) market grew 12 percent year-over-year (YoY), driven by long haul and metro applications. According to a newly published report by Dell'Oro Group for the trailing four quarter period, ending in the first quarter of 2014, Huawei, Ciena, and Alcatel-Lucent are the leaders in these segment, with ZTE recording the highest YoY growth.
“WDM sales have been amazingly robust over the past four quarters as service providers continue to add network capacity. While total optical market demand has entered positive growth during this period, the WDM market stands out as the true beneficiary of the increased investment. Furthermore, as 100 Gbps WDM transmission rates enter mainstream use, we don't see an end to its growth. We estimate that in the recent first quarter 2014 the number of 100 Gbps WDM line card shipments more than doubled versus the same period last year."
