D572-Type 1.5 µm Uncooled DFB FastLight Laser Module
for 2.5 Gbits/s and High Bandwidth Applications
Applications
s SONET OC-48/STM-16 systems
s Telecommunications
s Secure digital data systems
The low-profile D572-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)1510 nm or 1550 nm laser
with single-mode fiber pigtail
s Operating temperature range: –25 °C to +70 °C
(–25 °C to +85 °C versions under development)
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 Telcordia Technologies * TA-983 qualification pro-
gram
s Bandwidth > 3 GHz
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 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.
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 tee. A thermistor has been included for feedback
to board-level bias circuitry, if needed.
