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.

FEATUREs
■ 8-pin package suitable for SONET applications
■ Narrow linewidth, distributed feedback, multiquantum-well (DFB-MQW)1.3 µm laser with singlemode fiber pigtail
■ Choice of wide operating temperature ranges:  –40 °C to +85 °C or 0 °C to +85 °C
■ No TEC required
■ High output power: typical 2.0 mW peak power  coupled into single-mode fiber
■ Hermetically sealed active components
■ Internal back-facet monitor
■ Built-in thermistor and bias T
■ 25 Ω input impedance
■ Internal isolator
■ Qualification program: Telcordia Technologies*  TA-983

APPLICATIONs
■ SONET OC-48/STM-16 systems
■ Telecommunications
■ Secure digital data systems

Benefits
■ 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
