Description
The D572-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)1510 nm or 1550 nm laser  with single-mode fiber pigtail
■ Operating temperature range: –25 °C to +70 °C (–25 °C to +85 °C versions under development)
■ 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
■ Telcordia Technologies* TA-983 qualification program
■ Bandwidth > 3 GHz

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

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