The A371-Type Uncooled Isolated Laser Module con-
sists of a laser diode coupled to a single-mode fiber
pigtail. The device is available in a standard, 8-pin con-
figuration (see Figure 1 and/or Table 1) and is ideal for
CATV applications.

The module includes a narrow linewidth (<1 nm), DFB-
MQW, single-mode laser and an InGaAs PIN photo-
diode back-facet monitor in a hermetically sealed pack-
age.

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 pho-
todiode 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 manufac-
turing process from the Optoelectronics unit of Lucent
Technologies Microelectronics Group. Laser 2000 is a
low-cost platform that targets high-volume manufactur-
ing and tight product distributions on all optical subas-
semblies. This platform incorporates an advanced
optical design that is produced on Opto’s highly auto-
mated production lines. The Laser 2000 platform is
qualified for 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.

Handling Precautions
Caution: This device is susceptible to damage as a result of electrostatic discharge (ESD).Take proper
precautions during both handling and testing. Follow guidelines such as JEDEC Publication No.
108-A (Dec. 1988).
Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD.

Electro/Optical Characteristics (continued)
Analog Operation
The A371-Type Laser Module has the capability of being used in a wide variety of analog operations. These may
include several channels of pure video signals, or a mix of video signals with digital data channels riding on analog
carriers. It is difficult to prepare a single battery of testing conditions that will satisfy all applications. The following
table contains a set of testing conditions that Lucent believes will give a broad indication of the performance of the
A371 Series Laser Module. Please contact your local Field Application Engineer if different testing conditions and
parametric limits are required.
The distortion characteristics are measured using a two-tone test. The frequencies are 13 MHz and 19 MHz. The
second-order distortion components are measured at f1 + f2 = 32 MHz and f1 – f2 = 6 MHz. All third-order distor-
tion components are measured in the frequency range of 5 MHz—200 MHz, and they meet the required level. All
measurements are made with SC-SPC connectors on the laser module pigtails.
