The Lumentum S31 Series pump laser module’s revolutionary design and lean manufacturing
processes signifcantly advance the 980 nm pumps’ performance and scalability. It meets the
telecommunications industry’s stringent requirements, including Telcordia GR-468-CORE for
hermetic 980 nm pump modules.

The S31 Series pump module, which uses fber Bragg grating
stabilization to lock the emission wavelength, provides a
noise-free, narrowband spectrum, even under temperature, drive
current, and optical feedback changes. Wavelength selection is
available for applications requiring the highest spectrum control
performance with the highest power available.
