Data Sheet January 1999 D371-Type Digital Uncooled DFB Laser Module Applications s s s Long-reach SONET OC-3/OC-12 systems Telecommunications Secure digital data systems Benefits s s s s Easily board mounted Requires no lead bending No additional heat sinks required Pin compatible with industry-standard, 14-pin laser module Highly efficient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption The low-profile D371-Type Laser Module is ideally suited for short- and long-haul SONET and other high-speed digital applications. s Features s s Eight-pin package suitable for SONET applications Narrow linewidth, distributed-feedback, multiquantum-well (DFB-MQW)1.3 µm laser with singlemode fiber pigtail Wide operating temperature range: –40 °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 Qualification program: Telcordia Technologies * TA-983 Description The D371-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 laser diode is a narrow linewidth (<1 nm) DFBMQW single-mode laser and an InGaAs PIN photodiode back-facet monitor in an epoxy-free, hermetically sealed package. s s s s s s * Telcordia Technolog...
