Fiber Optic Rotary Joints

Multi-Channel FORJ

Fiber Optic Rotary Joints (FORJ) are to optical signals what electrical slip rings are to electrical signals, a means to pass signals across rotating interfaces, particularly when transmitting large amounts of data. FORJs maintain the intrinsic advantages of fiber end to end. Moog has been producing Fiber Optic Rotary Joints for over twenty years.
