D371

The D371-Type Uncooled Laser Module consists of a laser diode coupled to a single-mode fiber pigtail. The D371 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 InGaAs PIN photodiode back-facet monitor in an epoxy-free, hermetically sealed package.

The D371 characteristics listed in this document are met at 2.0 mW output power. Higher- or lower-power operation is possible. Under conditions of a fixed photodiode current, the change in optical output is typically ±0.5 dB over an operating temperature range of 40°Cto +85°C.

The D371 incorporates the new Laser 2000 manufacturing process developed by the Optoelectronic unit of Agere Systems Inc. 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 qualified for the central office and uncontrolled environments, and can be used for applications requiring high performance and low cost.
