Up to 500 mW Fiber Bragg Grating Stabilized 980 nm Pump Modules
2900 Series
Key Features
• Very high kink-free powers to 500 mW
• Low-profile, epoxy-free, and flux-free 14-pin butterfly
planar package with PM fiber
• Fiber Bragg grating stabilization
• Wavelength selection available
• 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
The JDSU 2900 Series 980 nm pump module utilizes a planar construction with
chip on subcarrier. The high power JDSU 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 2900 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 itsintended 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 Imax may lead to early device failure.
