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 Telcordia™ GR-468-CORE for hermetic
980 nm pump modules.
The 2700 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.

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 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 us-
ing power supplies, the laser diode should be
connected with the main power on and the out-
put voltage at zero. The current should be in-
creased slowly while monitoring the laser diode
output power and the drive current. Careful at-
tention to heatsinking and proper mounting of
this device is required to ensure specified per-
formance 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.
Labeling
21 CFR 1040.10 Compliance
Because of the small size of these devices, the output power and laser emission indicator
label shown below is attached to the individual shipping container. All labels are illustrated
here to comply with 21 CFR 1040.10 as applicable under the Radiations Control for Health
and Safety Act of 1968.
