Description

The D370-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-haul (SONET) and other digital applications.

The module includes a multiquantum-well Fabry­Perot (MQW F-P) laser and an InGaAs PIN photo­diode back-facet monitor in an epoxy-free, hermeti­cally sealed package.

D370-Type Digital Uncooled Laser Module October 2000

Description

(continued)

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 manufac-

turing process from the Optoelectronic Products unit of
Agere Systems Inc. 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 Agere Systems’ highly automated produc­tion lines. The laser 2000 platform is qualified for the

43 12

56 87

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.
