Fiber Optic Rotary Joints

FO190

Multi-Channel FORJ

The FO190 is a multipass fiber optic rotary joint (FORJ) for 2 to 21 multimode fibers. It is passive and bidirectional and allows the transfer of data, video and other signals on separate fibers across rotational interfaces.

The FO190 can be combined with our electrical and / or fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.

Other options include fluid-filling for pressure compensation permitting operation at any ocean depth, and the combination of the FO242 to include up to 6 singlemode passes.
