Is there any kind of Ethernet cable splitter that sends the identical data to multiple outputs?

I have a headphone mixer system (hearback) that uses cat5e to send audio to individual mixers. These cables are sending identical data, so I wondered if rather than running multiple Ethernet cables the length of the studio, I could run a single cable that would split in the room.

A switch won’t work - it needs to be the exact output of the rack unit. The data only flows one way.

Thanks!
