Can this work through multiple network switches? I want my sonos connect in network closet and optical run through my network to my fam room and basem

No, this is a point to point device (with a single ethernet cable between them), it does not transmit over TCP/IP and thus cannot be used through switches.

Do you have a model that combines hdmi and optical audio into a single transmitter and receiver unit?
