D372-Type Digital Uncooled DFB Laser Module for 2.5 Gbits/s Applications Applications SONET OC-48/STM-16 systems Telecommunications Secure digital data systems Easily board mounted Gull wing leads No additional heat sinks required Low-cost alternative to industry-standard, 14-pin isolated laser module (ILM) Highly efficient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption The low-profile D372-Type Laser Module is ideally suited for OC-48 SONET and other high-speed digital applications. Features8-pin package suitable for SONET applications Narrow linewidth, distributed feedback, multiquantum-well (DFB-MQW)1.3 �m laser with singlemode fiber pigtail Choice of wide operating temperature ranges: �C No TEC required High output power: typical 2.0 mW peak power coupled into single-mode fiber Hermetically sealed active components Internal back-facet monitor Built-in thermistor and bias T 25 input impedance Internal isolator Qualification program: Telcordia Technologies * TA-983 DescriptionThe 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 configuration (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 input impedance and allows for dc biasing through an internal bias T. A thermistor has been included for feedback to board-level bias circuitry, if needed. * Telcordia Technologies is a registered trademark of Telcordia Technologies, Inc.Table 1.

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 to +85 �C. This device incorporates the new laser 2000 manufacturing process from the Optoelectronic Products unit of Agere Systems Inc.. Laser 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 applications requiring high performance and low cost. Figure 1. D372-Type Digital Uncooled DFB Mini 8-Pin Laser Module Schematic, Top ViewStresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Take proper precautions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A (Dec. 1988). Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD. Table 2.
