The JDSU near infrared fused coupler splits or combines light at any selected
wavelength from 700 to 1150 nm. Designed for applications in fiber laser, sensor
and avionics applications, the coupler utilizes low loss fused fiber technology. No
light leaves the fiber and therefore no alignment is required; and there are no
unwanted reflections. Furthermore the output fiber pigtails may be directly
integrated into beam delivery systems.

现代大型集成电路，比如CPU、大型FPGA等消耗的电流往往达到数安到几十A，并且一些复杂系统电源种类繁多，因此电源系统的设计是否合理往往成为系统能否稳定工作的关键。电源系统的设计应该包含电源评估、电源供电电路设计和功率分布系统（Power distribution system 简称PDS）三个方面。本文分别探讨这三个方面的一般设计方法和思路。
一、电源评估 评估电源是电源系统设计的第一步，...[详细]
