JDSU 2700-TE User Manual

COMMUNICATIONS COMPONENTS

Key Features

• High kink-free powers to 300 mW

• Low-profile, epoxy-free, and flux-free 14-PIN butterfly
planar package

• Fiber Bragg grating stabilization

• Wavelength selection available

• Tight tracking of fiber-coupled power

• Integrated thermoelectric cooler, thermistor, and
monitor diode

• High dynamic range

• Excellent low power stability

The JDSU 2700-TE Series 980 nm pump module utilizes a planar construction
with chip on subcarrier. The high power JDSU laser chip is hermetically sealed in
a low-profile, epoxy- and flux-free 14-pin butterfly package and 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-TE Series pump module uses fiber Bragg grating stabilization to “lock”
the emission wavelength. It provides a noise-free narrowband spectrum, even
under changes in temperature, drive current, and optical feedback. Wavelength
selection is available for applications that require the highest performance in
spectrum control with the highest available powers.

The 2700-TE Series design also offers tight tracking of fiber-coupled power via the
monitor diode signal.

Applications

• Erbium doped fiber amplifiers (EDFAs)
without a front-fiber tab for tracking

• Dense wavelength division
multiplexing (DWDM) EDFAs for
small package designs

• High bit rate, high channel count EDFAs

• CATV distribution

Compliance

• Telcordia GR-468-CORE

Note: 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.

Traceability is accomplished through product serial number.

2. The maximum operating power P

op will be achieved at a device-specific current, the maximum operating current Iop. The individual value of Iop is noted on the hardcopy data sheet shipped with the device.

All values of I

op are limited by the maximum value listed in Table 2.

3. The pump laser shall never be operated at a power higher than the maximum operating power P

op throughout its lifetime. At Begin of Life (BOL), the operating current shall never be higher than the

device-specific maximum operating current I

op that is noted on the hardcopy data sheet shipped with the device. At End of Life (EOL), the operating current shall never be higher than the device-specific

kink-free current I

max that is noted on the hardcopy data sheet shipped with the device.

4. The module is kink-free (at least) up to a minimum kink-free power P

max that the module will achieve at a device-specific current, the kink-free current Imax. The individual value of Imax is noted on the

hardcopy data sheet shipped with the device. All values of I

max are limited by the maximum value listed in Table 2.

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 P

op 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 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 ensure 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 — 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.
