Last year, the use of pump-LD modules reached just over $70 million in telecommunications applications. Driven primarily by the deployment of OFAs in China, the Japan/Pacific Rim pump-LD-module market will increase in value to a leading $424 million in year 2013.

Montgomery believes DWDM will begin to make "a noticeable comeback." DWDM-rated OFAs typically will use more 1480-nm pumps versus 980-nm pump-laser modules. The 980-nm pump modules also are used in metro/access OFAs, but 1480-nm pump-LD modules with an output power capability of >200 mW will eventually take the market share lead, mainly used in WDM networks, adds Montgomery.
