DUAL-LOOP LASER DIODE DRIVER
Jul 2001Analog Devices Inc.Request Info
A dual-loop laser diode driver offered by Analog Devices Inc. features multirate operation from 155 Mb/s to 2.7 Gb/s. The company says its dual-loop control enables consistent optical performance over a wide range of temperatures and operating conditions. The ADN2841 continuously senses the optical output and corrects for variations caused by changes in operating temperature and laser diode degradation. This feature makes it suitable for uncooled applications and for those requiring long-term performance stability and reliability. The dual-loop architecture allows the driver to work with standard monitor photodiodes without data format limitations.
