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 configuration (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 Ω input impedance and allows for dc biasing through an internal
bias tee. A thermistor has been included for feedback
to board-level bias circuitry, if needed.

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
photodiode current, the change in optical output is typically ± 0.5 dB over an operating temperature range of
–25 ° C to +70 ° C.
This device incorporates the new Laser 2000 manufacturing process from the Optoelectronic Products unit of
Lucent Technologies Microelectronics Group. Laser
2000 is a low-cost platform that targets high-volume
manufacturing and tighter product distributions on all
optical subassemblies. This platform incorporates an
advanced optical design that is produced on one of the
highly automated production lines at the Opotelectronic
manufacturing facility. 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 absolute 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.
