This is hybrid rotary joint, it consists of power part, signal part, Gigabit Ethernet signal and fiber optical. obviously, one fiber optical single mode channel with low insertion loss but high return loss. one channel Gigabit Ethernet signal combine power channels, stable transmission, no package loss, no cross talk, low loss, reliable performance. For the shape structure, we can see housing material is aluminum alloy with solid shaft structure.
