Advance Data Sheet February 2000 D572-Type 1.5 µm Uncooled DFB FastLight ™ Laser Module for 2.5 Gbits/s and High Bandwidth Applications Applications s s s SONET OC-48/STM-16 systems Telecommunications Secure digital data systems Benefits s s s s 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 s The low-profile D572-Type Laser Module is ideally suited for OC-48 SONET and other high-speed digital applications. Features s s 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 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. 8-pin package suitable for SONET applications Narrow linewidth, distributed feedback, multiquantum-well (DFB-MQW)1510 nm or 1550 nm laser with...
