Up to 660 mW Fiber Bragg Grating Stabilized 980 nm Pump Modules
3000 Series
Key Features
• Very high kink-free powers to 660 mW
• Low-profile, epoxy-free, and flux-free 14-pin butterfly
planar package with PM fiber
• Fiber Bragg grating stabilization
• Multiple wavelength availability
• Integrated thermoelectric cooler, thermistor, and monitor diode
• High dynamic range
• Excellent low-power stability
Applications
• Next-generation dense wavelength
division multiplexing (DWDM)
erbium doped fiber amplifiers
(EDFAs) requiring the highest power
with “locked” wavelength emission
• Reduced pump-count EDFA
architectures
• Very long distance cable television
(CATV) trunks and very high node-
count distribution
• Pump splitting (multiple EDFA stages)
• FTTx, Agile metro/ROADM
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.

Note: Each device is rated to a maximum kink-free current (I
max
), provided on the individual datasheet. This is the maximum current under which the device will perform its intended function. Operation
above I
max
, and up to the absolute maximum rating, may result in poor device performance, and degrade device reliability. Long-termoperation above I
max
may lead to early device failure.
