REDWOOD CITY, Calif. – May 27, 2014 –According to a newly published report by Dell’Oro Group, the trusted source for market information about the networking and telecommunications industries, the total Wavelength Division Multiplexer or WDM market, comprising long haul and metro applications, grew 12 percent year-over-year in the trailing four quarter period, ending in the first quarter of 2014.

“WDM sales have been amazingly robust over the past four quarters as service providers continue to add network capacity,” said Jimmy Yu, Vice President of Optical Transport research at Dell’Oro Group.  “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,” added Mr. Yu.

The market share leaders for the trailing four quarter period, which includes the second quarter 2013 through the first quarter 2014, are listed in the following table.
