Abstract: To avoid multiple IC 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.

A similar version of this article appeared in the August 2, 2007 issue of Electronic Design magazine.

Small-form-factor pluggable modules (SFP modules) are in common use for the physical-layer interface in telecom and data-
communications equipment. Also common in these systems is an IC bus for the MDIO interface (Management Dat……
