48-1540-4000-BS - JDS Uniphase - Datasheet.Directory

COMMUNICATIONS COMPONENTS

Key Features • High power up to 4 W

• 100 µm aperture, 0.2 NA

• Low power dissipation

• Compact package design: 13 (Ø) x 12 mm (H)

• -5 to 70 °C operating range

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 µm 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.

Applications

• Er/Yb co-doped double cladding

fiber pumping

• Yb doped fiber laser pumping

• High power EDFAs for CATV and FTTx

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.
