3 / 8 page Data Sheet October 2000 D370-Type Digital Uncooled Laser Module 3 Agere Sysems Inc. Handling Precautions Caution: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper pre- cautions 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. Electrical/Optical Characteristics * Higher and lower powers available. See Table 4 for more information. † 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.
