Fibre Optic Rotary Joints are the optical equivalent of the electrical slip ring. It allows uninterrupted transmission of an optical signal while rotating along the fibre axis. A FORJ’s only function is to provide connection between two or multiple fibre cables whilst allowing free rotation between them. Therefore, it is critically important to ensure that the device has low insertion loss, small insertion loss variation (wow), and high return loss (a measure that characterises the amount of reflection a FORJ generates).
Combined with electrical slip rings, FORJ’s add a new dimension to traditional rotary joints. FORJ’s can be combined with proven Trolex Slip Rings to future-proof systems allowing ample bandwith to the end user.
