A370-Type Analog
Uncooled Laser Module
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 backfacet 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 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 from the Optoelectronics unit of Lucent
Technologies Microelectronics Group. Laser 2000 is a
low-cost platform that targets high-volume manufacturing and tight product distributions on all optical subassemblies. 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 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.

Electro/Optical Characteristics (continued)
Analog Operation
The A370 Series 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
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 distortion 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.
