3 / 8 page Advance Data Sheet D571-Type Digital 1.5 µm Uncooled DFB April 2000 FastLight Laser Module 3 Lucent Technologies Inc. Handling Precautions CAUTION: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper precautions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A (Dec. 1988). Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD. Electro-Optical Characteristics * 1mW power option also available. See Table 4 for more information. † BOL value; EOL = 80 mA. ‡ The slope efficiency is used to calculate the modulation current for a desired output power. This modulation current plus the threshold current comprise the total operating current for the device. § VR = reverse voltage. Table 2.
