Fiber Optic Rotary Joints

Fiber Optic Rotary Joint adopts fiber optic as media, providing the best technical solution for the transmission of data. It is especially suitable for equipments that require unlimited, continuous or intermittent rotation, transmitting large capacity of data and signals from the stationary position to the rotary position. It can improve mechanical performance, simplify system operation, and avoid damage to fiber optic due to the rotation of moving joints. The fiber optic rotary joint can be used together with a traditional electric slip ring, so as to make a photoelectric hybrid slip ring for the transmission of power and high speed data.

Fiber Optic Rotary Joints
Fiber Optic Rotary Joints (FORJs) 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. JINPAT has been producing Fiber Optic Rotary Joints for over Twenty-five years.

Single or Multi-Channel

FORJs are available in single and multi-channel options. The most cost and size efficient options are the single and dual channel designs. If more than two fibers are present in a system, multiplexing solutions are available to combine multiple channels onto one or two fibers to allow the use of a one or two channel FORJ.
