1 / 8 page Advance Data Sheet February 2000 D572-Type 1.5 µm Uncooled DFB FastLight ™ Laser Module for 2.5 Gbits/s and High Bandwidth Applications The low-profile D572-Type Laser Module is ideally suited for OC-48 SONET and other high-speed digital applications. Features s 8-pin package suitable for SONET applications s Narrow linewidth, distributed feedback, multiquan- tum-well (DFB-MQW)1510 nm or 1550 nm laser with single-mode fiber pigtail s Operating temperature range: –25 °C to +70 °C (–25 °C to +85 °C versions under development) s No TEC required s High output power: typical 2.0 mW peak power coupled into single-mode fiber s Hermetically sealed active components s Internal back-facet monitor s Built-in thermistor and Bias T s 25 Ω input impedance s Internal isolator s Telcordia Technologies * TA-983 qualification pro- gram s Bandwidth > 3 GHz Applications s SONET OC-48/STM-16 systems s Telecommunications s Secure digital data systems Benefits s Easily board mounted s Gull-wing leads s No additional heat sinks required s Low-cost alternative to industry-standard, 14-pin isolated laser module (ILM) s Highly efficient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption Description The D572-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 Ω input imped- ance 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. |
