Growing demands of cloud computing and high-definition video streaming are driving increases in server storage transmission speeds and in the transmission capacity of core networks. To meet these needs, the transmission speeds of physical-layer devices and modules need to increase, making signal integrity analysis even more important in assuring quality. Installing the 28/32G Multi-Channel PPG and ED Module offers PCBs high-speed interconnects up to 32.1 Gbit/s, BER measurements for device R&D, and simultaneous measurement of crosstalk between multi-channels, for more accurate signal integrity analysis.
