Multi-channel hollow fiber rotating connector

The invention discloses a multi-channel hollow fiber rotating connector comprising an input end plate, a fixed sleeve, a receiving end plate, a light shielding cylinder and a hollow annular cone. Three groups of to-be-transmitted signals enter the rotating connector at certain angles through three input channels arranged at different circumferences of an input end plate and are transmitted by means of reflection; when the signals are reflected by a certain number of times, the signals are emitted through three emitting windows at different circumferences of the hollow annular cone; the emittedsignals pass through three receiving end channels arranged at different circumferences of a receiving end plate and an output channel and then are coupled to a fiber collimator; and then the signalsare outputted by a transmission fiber. Compared with the prior art, the multi-channel hollow fiber rotating connector has the following beneficial effects: dynamic, off-axis and circumferential transmission of signals is reali
