D371-Type Digital Uncooled DFB
Laser Module
Applications
s Long-reach SONET OC-3/OC-12 systems
s Telecommunications
s Secure digital data systems
Benefits
The low-profile D371-Type Laser Module is ideally suited for
short- and long-haul SONET and other high-speed digital
applications.
Features
s Easily board mounted

module
s Highly efficient DFB-MQW laser structure allows
for lower threshold and drive currents, and reduced
power consumption
s Eight-pin package suitable for SONET applications
s Narrow linewidth, distributed-feedback, multiquan-
tum-well (DFB-MQW)1.3 µm laser with single-
mode fiber pigtail
s Wide operating temperature range:
–40 °C to +85 °C
s No TEC required
s High output power: typical 2.0 mW peak power
coupled into single-mode fiber
s Hermetically sealed active components
s Internal back-facet monitor
s Qualification program: Telcordia Technologies *
TA-983
Description
The D371-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 config-
uration (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.

D371-Type Digital Uncooled DFB Laser Module
Data Sheet
January 1999
Description (continued)
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 pho-
todiode current, the change in optical output is typically
±0.5 dB over an operating temperature range of –40 °C
to +85 °C.
This device incorporates the new Laser 2000 manufac-
turing process developed by the Optoelectronic unit of
Agere Systems Inc. Laser 2000 is a low-cost platform
that targets high-volume manufacturing and tighter
product distributions on all optical subassemblies. The
platform incorporates an advanced optical design that
is produced on a highly automated production line. The
Laser 2000 platform is qualified for the central office
and uncontrolled environments, 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.
