3000 Series

      The JDSU 3000 Series 980 nm pump module uses a planar construction with chip on subcarrier. The high-power laser chip is hermetically sealed in a low-profile, epoxy- and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode. This product uses a polarization maintaining fiber (PMF) pigtail that allows excellent side mode supression ratios(SMSR) over a very wide dynamic range. The 3000 Series pump module uses PM fiber Bragg grating stabilization to "lock" the emission wavelength. It provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers.
      they could be used in the following fields: 1.Next-generation dense wavelength division multiplexing (DWDM) erbium doped fiber amplifiers (EDFAs) requiring the highest power with "locked" wavelength emission; 2.Reduced pump-count EDFA architectures; 3.Very long distance cable television (CATV) trunks and very high node-count distribution; 4.Pump splitting (multiple EDFA stages); 5.FTTx, Agile metro/ROADM.
      The JDSU 3000 Series have many features: 1.Very high kink-free powers to 660 mW;2.Low-profile, epoxy-free, and flux-free 14-pin butterfly planar package with PM fiber; 3.Fiber Bragg grating stabilization; 4.Multiple wavelength availability; 5.Integrated thermoelectric cooler, thermistor, and monitor diode; 6.High dynamic range; 7.Excellent low-power stability.
