D571-20A Datasheet | Agere Systems

Features s s Eight-pin package suitable for SONET/SDH applications Narrow linewidth, distributed-feedback, multiquantum-well (DFB-MQW), 1510 nm or 1550 nm laser with single-mode fiber pigtail Available in narrow and wide temperature ranges No TEC required High output power: - Typical 2.0 m W peak power coupled into singlemode fiber - 1.0 m W devices are also available s 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. The laser diode is a narrow linewidth (<1 nm) DFBMQW single-mode laser and an In Ga As PIN photodiode back-facet monitor in an epoxy-free, hermetically sealed package. s s s D571-Type Digital 1.5 µm Uncooled DFB Fast Light Laser Module Advance Data Sheet April 2000 qualified for the central office and uncontrolled environments, and can be used for applications requiring high performance and low cost.

Higher- or lower-power operation is possible. Under conditions of a fixed photodiode current, the change in optical output is typically ±0.5 d B over an operating temperature range of - 40 °C to +85 °C. This device incorporates the new Laser 2000 manufacturing process developed by the Optoelectronic unit of Lucent Technologies Microelectronics Group. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tighter product distributions on all optical subassemblies. The platform incorporates an advanced optical design that is produced on a highly automated production line. The Laser 2000 platform is 4 3 2 1 1-900...
