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

Ω

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.

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 typi-

cally

0.5 dB over an operating temperature range of

–25

C to +70

This device incorporates the new Laser 2000 manufac-

turing 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 quali-

ﬁed for the central ofﬁce and uncontrolled environ-

ments, 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.
