D372-Type Digital Uncooled DFB
Laser Module for 2.5 Gbits/s Applications
Applications
s SONET OC-48/STM-16 systems
s Telecommunications
s Secure digital data systems
The low-profile D372-Type Laser Module is ideally suited for
OC-48 SONET and other high-speed digital applications.
Features
s 8-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 Choice of wide operating temperature ranges:
–40 °C to +85 °C or 0 °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 Built-in thermistor and bias T
s 25 input impedance
s Internal isolator
s Qualification program: Telcordia Technologies *
TA-983
Benefits
s Easily board mounted
s Gull wing leads
s No additional heat sinks required
s Low-cost alternative to industry-standard, 14-pin
isolated laser module (ILM)
s Highly efficient DFB-MQW laser structure allows
for lower threshold and drive currents, and reduced
power consumption
Description
The D372-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 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.
This package is optimized for a 25 input imped-
ance and allows for dc biasing through an internal
bias T. A thermistor has been included for feedback
to board-level bias circuitry, if needed.
