Product Bulletin
2800 Series Pumps Up to 360 mW fiber Bragg grating stabilized 980 nm pump modules
The JDS Uniphase 2800 Series 980 nm pump module represents the latest in chip and module technology. It utilizes our 6540 chip that offers the highest power with improved efficiency. The planar package with chip on subcarrier has superior performance for operating powers and operating current. The hermetically sealed package meets the stringent requirements of the telecommunications industry as well as the intent of TelcordiaTM GR-468-CORE for hermetic 980 nm pump modules. The 2800 Series pump module uses fiber Bragg grating stabilization to "lock" the emission wavelength and provides a noise-free narrow band 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. The combination of planar packaging with excellent thermal performance and the high performance 6540 chip is expected to set the trend for next generation of EDFA designs requiring the ultimate in distance and bandwidth. Key Features * Very high power to 360 mW * Low profile planar package * Fiber Bragg grating stabilized * Wavelength selection available * Integrated TEC and thermistor Applications * Next generation DWDM EDFAs requiring the highest power with "locked" wavelength emission * Enables reduced pump count EDFA architectures * Very long distance CATV trunks and very high node count distribution * Suitable for very high ambient temperatures Compliance * TelcordiaTM GR-468-CORE

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 WILL INCREASE EYE HAZARD. Operating the laser diode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with the component must be employed such that the maximum peak optical power cannot be exceeded. 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 insure 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 -- Electro-static discharge is the primary cause of unexpected laser diode failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous anti-static techniques when handling laser diodes. 21 CFR 1040.10 Compliance Because of the small size of these devices, each of the labels shown is attached to the individual shipping container. They are illustrated here to comply with 21 CFR 1040.10 as applicable under the radiations control for health and safety act of 1968.
