摘　　要：40Gbit/sSDH设备中涉及大量的高速和超高速信号,文章从硬件设计角度分析了影响信号完整性的因素,并且从电源分配、传输线设计、串扰和电磁干扰4个方面加以阐述.There are a great deal of high-speed and ultra high-speed signals to be treated in 40 Gbit/s SDH equipment. In this paper the factors that affect signal integrity are studied from the angle of hardware design. It is expatiated in four aspects: power distribution, transmission line design, crosstalk and electro-magnetic interference.
