Benefits
s 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 efficient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption
The low-profile 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 fiber pigtail. The device is available in a standard, 8-pin configuration (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...
