Description

The D374-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 configu- ration (see Figure 1 and/or Table 1) and is ideal for short-reach and other high-speed digital applica- tions. It is developed specifically for 2.5 Gbits/s appli- cations. The module includes a multiquantum-well Fabry- Perot (MQW F-P) laser and an InGaAs PIN photo- diode back-facet monitor in an epoxy-free, hermeti- cally sealed package.

D374-Type Digital Uncooled 2.5 Gbits/s Laser Module December 2000 22 Agere Systems Inc. (continued) The device characteristics listed in this document are met at 1.0 mW output power. Higher- or lower-power operation is possible. Under conditions of a fixed pho- todiode current, the change in optical output is typically 0.5 dB over an operating temperature range of –40 C to +85 This device incorporates the new Laser 2000 manufac- turing process developed by the Optoelectronic unit of Agere Systems Inc. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tight prod- uct distributions on all optical subassemblies. This plat- form 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. Table 1. Pin Descriptions
