D372-Type Digital Uncooled DFB

Laser Module for 2.5 Gbits/s Applications

Applications

SONET OC-48/STM-16 systems

Telecommunications

Secure digital data systems

Bene鏗乼s

Easily board mounted

Gull wing leads

No additional heat sinks required

Low-cost alternative to industry-standard, 14-pin

isolated laser module (ILM)

Highly ef鏗乧ient DFB-MQW laser structure allows

for lower threshold and drive currents, and reduced

power consumption

The low-pro鏗乴e D372-Type Laser Module is ideally suited for

OC-48 SONET and other high-speed digital applications.

Description

The D372-type uncooled laser module consists of a

laser diode coupled to a single-mode 鏗乥er pigtail.

The device is available in a standard, 8-pin con鏗乬u-

ration (see Figure 1 and/or Table 1) and is ideal for

long-reach (SONET) and other high-speed digital

applications.

The module includes a narrow linewidth (<1 nm),

DFB-MQW single-mode laser and an InGaAs PIN

photodiode back-facet monitor in a hermetically

sealed package.

This package is optimized for a 25

鈩?/div>

input imped-

ance and allows for dc biasing through an internal

bias T. A thermistor has been included for feedback

to board-level bias circuitry, if needed.
