This product is a compact single-channel Fiber Optic Rotary Joint (FORJ), also known as a fiber optic slip ring or optical rotary union. It transmits optical signals between a stationary structure and a continuously rotating platform without twisting the fiber. The device features a precision-machined stainless steel cylindrical housing with gold-toned bearing/sealing rings, a four-hole square mounting flange for secure installation, a front rotating interface, and a rear fiber pigtail (green jacket, typically indicating APC polishing) for connection to the optical system. Precision internal alignment of the fixed and rotating fibers ensures low insertion loss and minimal loss variation during 360° continuous rotation, making it ideal for demanding rotating optical link applications.
