Fiber optical slip ring is also called Fiber Optical Rotary Joint, FORJ or optical slip ring. Fiber optic lines serve as a statistical broadband access technology to handle data transfer between rotating connected system components. Especially suitable for places where infinite, continuous or intermittent rotation is necessary and large spatial statistics must be transferred from a fixed position to a rotating position.

The benefits of fiber optic slip rings: high integration, light weight, a variety of packaging methods, very low pullout loss and return loss. In the case of strong magnetic current interference, it can also work normally, completely free from electromagnetic induction hazards, and has an excellent safety factor. The optical fiber slip ring has high-precision spare parts, and the probability of deciphering the signal through the entire transmission link is basically zero. Optical signal propagation is not reversible transmission. When the fiber optical slip ring is working, it is friction less and has a long service life, and some lifespan can reach 300 million revolutions.
