Homebrew fiber optic loop cable

Very simple homebrew fiber optic “loop” cable. The D2B devices have to form a loop and this little gizmo comes very handy if you have to disconnect a device – just plug the loop in the empty fiber optic socket.

The connector is 3D printed, the optical “cable” is cut from SP-DIF (aka TOSLINK) cable – they use the same 1mm plastic fiber core.
