This bundle includes everything you need to set up an optically-isolated Roon endpoint. The opticalRendu is already setup to run Roon, i.e., "Roon Ready." It comes with its own 7v linear power supply, fiber ethernet convertor with power supply, fiber ethernet cable and SFP module.

Please note that this is the "Lite" version of the OpticalRendu, which means it can only be set up as a Roon endpoint.  If, like me, Roon is your primary streaming source, then this will not be an issue.  Here is a description from Sonore's website:

The Sonore opticalRendu project is an extension of the microRendu and ultraRendu projects that came before it. The design is inspired by audiophile gear and meant to bring grace and simplicity to a microcomputer. The original microRendu was very small and intended to be hidden out of sight behind your other gear. The opticalRendu can be powered by your favorite power supply. The opticalRendu has optical Ethernet input and USB-Audio output with all the connectors located on the rear of the unit for easy cable routing. The opticalRendu utilizes a new proprietary printed circuit board with only the essential components and many updates to match its optical designation.
