请问SFI是什么东西？求助！以下是相关的资料。对了，我是做收发器和光端机的，这应该和模块有关，向大虾们求救。多谢！
SFI signaling is based on differential high speed lowvoltage logic with AC-couplingin the module. SFI was developed with the primary goal of low power and low electromagnetic interference (EMI). To satisfy this requirement the nominal differential signal levels are ~500 mV p-p with edge speed control to reduce EMI. |
