Description
The D571-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
■ Eight-pin package suitable for SONET/SDH applications
■ Narrow linewidth, distributed-feedback, multiquan tum-well (DFB-MQW), 1510 nm or 1550nm laser with single-mode fiber pigtail
■ Available in narrow and wide temperature ranges
■ No TEC required
■ High output power:
— Typical 2.0 mW peak power coupled into single-mode fiber
— 1.0 mW devices are also available
■ Hermetically sealed active components
■ Internal back-facet monitor

APPLICATIONs
■ Long-reach SONET OC-3/STM-1, OC-12/STM-4 systems
■ Telecommunications
■ Secure digital data systems
