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
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
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.
