App Note: Analog switch multiplexes SFP modules

rsdio writes: There is probably a way to implement this circuit with any analog mux instead of the Maxim part… Analog Switch Multiplexes SFP Modules To avoid multiple I²C bus masters in a telecom or data-communications system with SFP modules, add an analog multiplexer (MAX4572) that directs the data line to the appropriate SFP module.
