COMMUNICATIONS COMPONENTS Uncooled Multi-Mode Pump Module 4800 Series Key Features * High power up to 4 W * 100 m aperture, 0.2 NA * Low power dissipation * Compact package design: 13 (O) x 12 mm (H) * -5 to 70 C operating range Applications * Er/Yb co-doped double cladding fiber pumping * Yb doped fiber laser pumping * High power EDFAs for CATV and FTTx The JDSU 4800 Series 915 nm and 939 nm uncooled multi-mode pump modules simplify next-generation high-power erbium doped fiber amplifier (EDFA) designs for CATV and FTTx applications by eliminating the need for larger, less efficient, and costlier thermoelectric coolers and their control circuitry. The 4800 Series single-emitter fiber-coupled laser diodes offer up to 4 W power from a 100 m fiber into 0.2 NA in an operating temperature range of -5 to 70 C. The 4800 Series pump module incorporates the JDSU 6390 laser diode for unmatched performance and reliability at high temperatures and power levels. Leveraged from the single-mode 980 nm telecom design, this package shares the same field-proven L3 platform and demonstrates excellent long term reliability. The 4800 Series pump module is tested to Telcordia GR-468-CORE and meets the intended requirements of this telecommunication components standard.

Sample: 48-1540-4000-BS Product Code 48-1540-4000-BS 48-3940-4000-BS Description 895 to 935 nm, 4 W, with base plate 919 to 959 nm, 4 W, with base plate 4800 SERIES 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 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. 48-ABC123 Serial: DANGER 48-ABC123 INVISIBLE LASER RADIATION* Model: AVOID EYE OR SKIN EXPOSURE TO DIRECT OR SCATTERED RADIATION GaAlAs Diode CW Serial Number Identification Label 48-xxxx-xxxx-xx 8 W max.
