Fiber Optic Rotary Joint

FO300

Single Channel FORJ

The FO300 is a multi-pass fiber optic rotary joint (FORJ). It allows the transfer of optical signals across a rotational interface and is passive and bidirectional. The smaller version “A” accommodates up to 19 separate singlemode or multimode optical fibers. The larger version “B” supports up to 31 separate channels. A third fluid-filled and pressure compensated version for up to 13 singlemode fibers is also available for use in subsea.

The FO300 can be combined with electrical and / or fluid slip rings, providing a single package for optical signals, electrical power and fluid transfer.
