D571-Type Digital 1.5 µm Uncooled DFB
FastLight Laser Module
s Hermetically sealed active components
s Internal back-facet monitor
s Qualification program: Telcordia Technologies *
TA-983
* Telcordia Technologies is a trademark of Bell Communications
Research, Inc.
Applications
s Long-reach SONET OC-3/STM-1, OC-12/STM-4
systems
s Telecommunications
s Secure digital data systems
The low-profile D571-Type Laser Module is ideally suited for
short- and long-haul SONET and other high-speed digital
applications.
Features
s Eight-pin package suitable for SONET/SDH
applications
s Narrow linewidth, distributed-feedback, multiquan-
tum-well (DFB-MQW), 1510 nm or 1550 nm laser
with single-mode fiber pigtail
s Available in narrow and wide temperature ranges
s No TEC required
s High output power:
— Typical 2.0 mW peak power coupled into single-
mode fiber
— 1.0 mW devices are also available
Benefits
s Easily board mounted
s Requires no lead bending
s No additional heat sinks required
s Pin compatible with industry-standard 14-pin laser
module
s Highly efficient DFB-MQW laser structure allows
for lower threshold and drive currents, and reduced
power consumption
Description
The D571-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.
The laser diode is a narrow linewidth (<1 nm) DFB-
MQW single-mode laser and an InGaAs PIN photo-
diode back-facet monitor in an epoxy-free, hermeti-
cally sealed package.

Handling Precautions
CAUTION: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper
precautions during both handling and testing. Follow guidelines such as JEDEC Publication
No. 108-A (Dec. 1988).
Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD.
