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 Ω input impedance and allows for dc biasing through an internal bias tee. A thermistor has been included for feedback to board-level bias circuitry, if needed. * Telcordia Technologies is a trademark of Bell Communications Research, Inc. D572-Type 1.5 µm Uncooled DFB FastLight Laser Module for 2.5 Gbits/s and High-Bandwidth Applications Description (continued) Advance Data Sheet February 2000 Table 1. Pin Descriptions 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 typically ±0.5 dB over an operating temperature range of –25 °C to +70 °C. This device incorporates the new Laser 2000 manufacturing process from the Optoelectronic Products 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. 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. 4 3 2 1 5 6 7 8 Pin Number Connection 1 2 3 4 5 6 7 8 Thermistor Thermistor, package GND Laser dc bias cathode (–) choke Photodiode cathode Photodiode anode Laser diode anode (+) Laser RF input cathode (–) 25 Ω Laser diode anode (+) 1-900.b Figure 1.
