Applications

n SONET OC-48/STM-16 systems n Telecommunications n Secure digital data systems Benefits n Easily board mounted n Gull wing leads n No additional heat sinks required n Low-cost alternative to industry-standard, 14-pin isolated laser module (ILM) n Highly efficient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption

Description

The D372-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 long-reach (SONET) and other high-speed digital applications. The module includes a narrow linewidth (<1 nm), DFB-MQW single-mode laser and an InGaAs PIN photodiode back-facet monitor in a hermetically sealed package. This package is optimized for a 25 W input imped- ance and allows for dc biasing through an internal bias T. A thermistor has been included for feedback to board-level bias circuitry, if needed.

(continued) The device 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 typi- cally 0.5 dB over an operating temperature range of –40 C to +85 This device incorporates the new laser 2000 manufac- turing process from the Optoelectronic Products 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. This platform incorporates an advanced optical design that is produced on one of the highly automated production lines at the Opotelectronic manufacturing facility. The laser 2000 platform is qualified for the central office and uncontrolled environments, and can be used for appli- cations requiring high performance and low cost. Table 1. Pin Descriptions
