Fiber Optic Rotary Joints
Fiber optic rotary joints are used to pass optical signals across rotating interfaces, particularly for large amounts of data, are available in single and multi-channel options, can be combined with electrical slip rings to provide an integrated rotational interface for optical signals and electrical power. FORJs usually operate at 1300 nm to1550 nm wavelengths singlemode type and 850 nm to 1300 nm multimode type, support long distance data links under high shock and vibration or harsh environments. FORJs intrinsic advantages ensure they are not easy to be influenced by environment and achieve the reliable transmission, the rugged bodies allow fiber pigtails or ST, FC receptacles on either the rotor or the stator side.
