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 configuration (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) DFBMQW single-mode laser and an InGaAs PIN photodiode back-facet monitor in an epoxy-free, hermetically sealed package.

Table 1. Pin Descriptions
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 –40 °C
to +85 °C.

This device incorporates the new Laser 2000 manufacturing process developed by the Optoelectronic unit of
Agere Systems Inc. Laser 2000 is a low-cost platform
that targets high-volume manufacturing and tighter
product distributions on all optical subassemblies. The
platform incorporates an advanced optical design that
is produced on a highly automated production line. 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.
