Isolated outputs and data channels

A customer recently told us of an application where they needed to provide 5V and 12V isolated outputs and 4 isolated data channels at 1Mbps max, from an input supply of 5V.  The user can connect a load to either of the two outputs, but not both, to power an encoder from about 5V or 12V at about 100mA.  Right now they are using optocouplers for the design but seeing some limitations.  Do you have an alternative solution and how would it work?
