COMMUNICATIONS COMPONENTS
Up to 180 mW Fiber Bragg Grating Stabilized 980 nm Pump Modules 2600 Series
Key Features
* High kink-free powers to 180 mW * Low-profile, epoxy-free, and flux-free 14-PIN butterfly planar package * Fiber Bragg grating stabilization * Wavelength selection available * Integrated thermoelectric cooler, thermistor, and monitor diode * High dynamic range * Excellent low power stability
Applications
* Dense wavelength division multiplexing (DWDM) EDFAs for small package designs * High bit rate, high channel count EDFAs * CATV distribution
The JDSU 2600 Series of 980 nm pump modules utilizes a planar construction with chip on subcarrier. The high power JDSU laser chip is hermetically sealed in a low-profile, epoxy-free and flux-free 14-pin butterfly package, fitted with a thermistor, thermoelectric cooler, and monitor diode. The module meets the stringent requirements of the telecommunications industry, including TelcordiaTM GR-468-CORE for hermetic 980 nm pump modules. The 2600 Series pump module uses fiber Bragg grating stabilization to "lock" the emission wavelength and provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications requiring the highest performance in spectrum control with the highest powers available.
Compliance
* Telcordia GR-468-CORE

Note: Absolute maximum ratings are the maximum stresses that may be applied to the pump module for short periods of time without causing damage. Stresses in excess of the absolute maximum ratings can permanently damage the device. Exposure to absolute maximum ratings for extended periods, or exposure to more than one absolute maximum rating simultaneously may adversely affect device reliability.

1. The 27-xxxx-xxx may be substituted for this part series. All 26-xxxx-xxx end product specifications will remain as published; there is no change to part numbers, product testing, quality or reliability. Traceability is accomplished through product serial number. 2. The maximum operating power Pop will be achieved at a device-specific current, the maximum operating current Iop. The individual value of Iop is noted on the hardcopy data sheet shipped with the device. All values of Iop are limited by the maximum value listed in Table 2. 3. The pump laser shall never be operated at a power higher than the maximum operating power Pop throughout its lifetime. At Begin of Life (BOL), the operating current shall never be higher than the device-specific maximum operating current Iop that is noted on the hardcopy data sheet shipped with the device. At End of Life (EOL), the operating current shall never be higher than the device-specific kink-free current Imax that is noted on the hardcopy data sheet shipped with the device. 4. The module is kink-free (at least) up to a minimum kink-free power Pmax that the module will achieve at a device-specific current, the kink-free current Imax. The individual value of Imax is noted on the hardcopy data sheet shipped with the device. All values of Imax are limited by the maximum value listed in Table 2.

1. The Tracking Error is defined as the normalized change of output power relative to the operating power over case temperature range 0 C to 75 C, at constant back face monitor current corresponding to the operating power at 25 C. 2. The Tracking Ratio is a measure of the front-to-back tracking when the output power is varied. On a plot of optical power versus back-face photocurrent, a straight line is drawn between the minimum power (20 mW) and the operating power Pop points. The tracking ratio is defined as the ratio between measured optical power (shown as data points on the plot) to the value derived from the straight line.

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.
