摘要：在外行人的术语，本文介绍了基于光纤通信的日益增长的重要性，并说明实施这项技术正在使用的各种标准（ SDH ，SONET和FDDI ） 。作为一个年轻的技术，可以改进，既提高该技术的性能和降低成本，在生产过程中。数字电位器提供了一种手段，关键的激光驱动器和反馈电路设置为最佳性能。花盆内温度传感机制，可以用来作为温度的函数可能发生的任何参数变化的监测和补偿这些电路。这些数字电位器也可以用于自动化生产校准程序进行一次手动使用机械电位器或固定电阻挑选。这不仅降低了生产成本，这些激光驱动器也可以用来提高设备的可靠性和质量，消除人为错误的因素校准过程。达拉斯半导体电位讨论包括DS1845 ， DS1846 ， DS1847和DS1848 。Maxim > App Notes > DIGITAL POTENTIOMETERS FIBER-OPTIC CIRCUITS Keywords: SONET, SDH, ATM, FDDI, faster ethernet, gigabit ethernet, laser driver, digital pot, laser drivers, Oct 21, 2002 digital potentiometers, digi pots APPLICATION NOTE 1769 Behind the Light Show in Optical Transceivers Abstract: This article explains, in laymen's terms, the growing importance of optic-based telecommunications and describes the various standards (SDH, SONET, and FDDI) that are being used to implement this technology. As a young technology, improvements can be made to both improve the performance of the technology and reduce costs in manufacturing process. Digital potentiometers provide a means to set critical laser driver and feedback circuits for optimal performance. Temperature sensing mec……
