Description
The A370-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 CATV
applications.
The module includes a multiquantum-well Fabry-Perot
(MQW F-P) laser and an InGaAs PIN photodiode back-
facet monitor in an epoxy-free, hermetically sealed
package.
The device characteristics listed in this document are
met at 1.0 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 ov er an operating temperature r ange 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 sub-
assemblies. This platform incorporates an advanced
optical design that is produced on the Optoelectronic
unit’s highly automated production lines. The Laser
2000 platform is qualified for the central office and
uncontrolled environments, and can be used for appli-
cations 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 de vice is susceptible to dama ge as a result of electrostatic disc harge (ESD). Take proper pre-
cautions 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.

Analog Operation
The A370 Series Laser Module has the capability of being used in a wide variety of analog operations. These may
include se veral 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
A370 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.
* See Table 5 for more information.
