D372

Data Sheet December 2000 D372-Type Digital Uncooled DFB Laser Module for 2.5 Gbits/s Applications Applications s s s SONET OC-48/STM-16 systems Telecommunications Secure digital data systems Benefits 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 The low-profile D372-Type Laser Module is ideally suited for OC-48 SONET and other high-speed digital applications. s s Features s s s 8-pin package suitable for SONET applications Narrow linewidth, distributed feedback, multiquantum-well (DFB-MQW)1.3 µm laser with singlemode fiber pigtail Choice of wide operating temperature ranges: –40 °C to +85 °C or 0 °C to +85 °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 Ω input impedance Internal isolator Qualification program: Telcordia Technologies * TA-983 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 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...
