Difference Between the FORJ and RF Rotary Joints

Fiber optic rotary joints (FORJs) are used to transmit high-speed data signals over optical fibers in systems that require continuous rotation. FORJs allows optical signals to be transmitted between stationary and rotating parts of a system, without any signal loss or degradation. The FORJ typically consists of a stationary component, a rotating component, and a fiber optic assembly that allows the transmission of light through the rotating joint.

RF rotary joints are used to transmit high-frequency electrical signals between stationary and rotating parts of a system. RF rotary joints allow the transmission of electromagnetic energy through a rotating joint, without signal loss or interference. RF rotary joints typically consist of two or more conductive rings that rotate with the system, allowing electrical signals to be transmitted through the joint.
