D572-Type 1.5 µm Uncooled DFB FastLight ™ Laser Module
for 2.5 Gbits/s and High Bandwidth Applications
Applications
■ SONET OC-48/STM-16 systems
■ Telecommunications
■ Secure digital data systems
Benefits
■ Easily board mounted
■ Gull-wing leads
■ No additional heat sinks required
■ Low-cost alternative to industry-standard, 14-pin
isolated laser module (ILM)
■ Highly efficient DFB-MQW laser structure allows
for lower threshold and drive currents, and reduced
power consumption
The low-profile D572-Type Laser Module is ideally suited for
OC-48 SONET and other high-speed digital applications.
Features
Description
■ 8-pin package suitable for SONET applications
The D572-Type Uncooled Laser Module consists of a
laser diode coupled to a single-mode fiber pigtail.
The device is available in a standard, 8-pin configu-
ration (see Figure 1 and/or Table 1) and is ideal for
long-reach (SONET) and other high-speed digital
applications.
■ Narrow linewidth, distributed feedback, multiquan-
tum-well (DFB-MQW)1510 nm or 1550 nm laser
with single-mode fiber pigtail
■ Operating temperature range: –25 °C to +70 °C
(–25 °C to +85 °C versions under development)
The module includes a narrow linewidth (<1 nm)
DFB-MQW single-mode laser and an InGaAs PIN
photodiode back-facet monitor in a hermetically
sealed package.
■ No TEC required
■ High output power: typical 2.0 mW peak power
coupled into single-mode fiber
This package is optimized for a 25 Ω input imped-
ance and allows for dc biasing through an internal
bias tee. A thermistor has been included for feedback
to board-level bias circuitry, if needed.
■ Hermetically sealed active components
■ Internal back-facet monitor
■ Built-in thermistor and Bias T
■ 25 Ω input impedance

■ Internal isolator
■ Telcordia Technologies* TA-983 qualification pro-
gram
■ Bandwidth > 3 GHz

The device characteristics listed in this document are
met at 2.0 mW output power. Higher- or lower-power
operation is possible. Under conditions of a fixed
photodiode current, the change in optical output is typi-
cally ±0.5 dB over an operating temperature range of
–25 °C to +70 °C.

Lucent Technologies Microelectronics Group. Laser
2000 is a low-cost platform that targets high-volume
manufacturing and tighter product distributions on all
optical subassemblies. This platform incorporates an
advanced optical design that is produced on one of the
highly automated production lines at the Opotelectronic
manufacturing facility. The Laser 2000 platform is quali-
fied for the central office and uncontrolled environ-
ments, and can be used for applications requiring high
performance and low cost.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
