IdealPhotonics' rotating fiber optic patch cord is an integrated rotating joint optical transmission component. Through precision optical collimation design (such as a ceramic ferrule) and a low-torque mechanical structure (<0.1 N·m), it achieves 360° tangle-free signal transmission between the fiber and the device. Specifically designed for optogenetic experiments on free-moving animals, it ensures continuous and stable photostimulation.Parameters including rotational loss (<0.3 dB/360°), torque resistance (
