COMMUNICATIONS COMPONENTS
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 (Imax), provided on the individual datasheet. This is the maximum current under which the device will perform itsintended function. Operation above Imax, 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.

User Safety
Safety and Operating Considerations The laser light emitted from this laser diode is invisible and may be harmful to the human eye. Avoid looking directly into the fiber when the device is in operation. CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT INCREASES EYE HAZARD. Operating the laser diode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power. CW laser diodes may be damaged by excessive drive current or switching transients. When using power supplies, the laser diode should be connected with the main power on and the output voltage at zero. The current should be increased slowly while monitoring the laser diode output power and the drive current. Careful attention to heatsinking and proper mounting of this device is required to ensure specified performance over its operating life. To maximize thermal transfer to the heatsink, the heatsink mounting surface must be flat to within .001" and the mounting screws must be torqued down to 1.5 in.-lb. ESD PROTECTION -- Electrostatic discharge (ESD) is the primary cause of unexpected laser diode failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling laser diodes.
