COMMUNICATIONS COMPONENTS Uncooled Multi-Mode Pump Module 4900 Series Key Features • High output power up to 8 W • 105 µm aperture • 0.22 NA • Isolated electrical contacts • High reliability Applications • Er/Yb co-doped, double-clad fiber amplifiers • High-power EDFAs for CATV and FTTx NORTH AMERICA : 800 498-JDSU (5378) The JDSU 4900 Series uncooled multimode pump modules simplify nextgeneration, high-power erbium doped fiber amplifier (EDFA) designs for CATV and FTTx applications by eliminating the need for thermoelectric coolers and their control circuitry. The 4900 Series builds upon the field-proven success of the JDSU 4800 Series. The new pump features higher power in a smaller, coolerless footprint with isolated electrical pins for simplified thermal and electrical management. Up to 8 W of optical power from a 105 µm fiber pigtail makes the 4900 Series the ideal solution for the FTTx and CATV high-power EDFA pumping market. In addition, the 4900 Series takes advantage of existing global JDSU infrastructure to combine a highly reliable design with cost-effective manufacturing.

Avoid looking directly into the laser diode or into the collimated beam along its optical axis 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 power supplies are used, the laser diode should be connected with the main power on and the output voltage at zero. The current should be increased slowly while the laser diode output power and the drive current are monitored. Device degradation accelerates with increased temperature, and therefore careful attention to minimizing the case temperature is advised. For example, life expectancy will decrease by a factor of four if the case is operated at 50°C rather than 30°C. A proper heatsink for the laser diode on a thermal radiator will greatly enhance laser life. Firmly mount the laser on a radiator with a thermal impedance of less than 0.5°C/W for increased reliability. ESD PROTECTION - Electrostatic discharge 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. Labeling 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 Radiation Control for Health and Safety Act of 1968.
