3S Photonics of Marcoussis, Essonne near Paris has announced general availability and volume production of its 1999 PLM series of medium- and high-power (365mW kink-free) 980nm terrestrial pump laser modules, targeted at the metropolitan market. This follows January’s launch of its 1999 CHP series of ultra-high-power (660mW kink-free) 980nm pump laser modules.

The new family of terrestrial products (announced last December) leverages 3S’ expertise in pump lasers for submarine applications, says Yannick Bailly, VP of marketing, and also includes the low power 1999 PLU (outputting up to 275mW in an uncooled mini-DIL package). “By introducing the 1999 PLM series, we put ourselves in position to address every telecommunication market segment, from low to high powers,” adds Bailly.

The new FBG-stabilized 1999 PLM pump laser modules incorporate the latest-generation 1999 LCv1 high-power 980nm laser chip, which have been developed internally by 3S. The laser delivers more than 450mW at 600mA and is fully qualified in accordance with Telcordia GR-468 CORE specifications. Also included is an integrated thermo-electric cooler (TEC), precision NTC thermistor, and back-facet monitor photodiode.

The 1999 PLM is hermetically sealed in a low-profile 14-pin butterfly package with a single-mode fiber (SMF) pigtail.  
Applications include low-noise erbium-doped fiber amplifiers (EDFAs) and next-generation dense wavelength division multiplexing (DWDM) EDFAs.
