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
