Fiber Optic Rotary Joint

FO197

Single Channel FORJ

The FO197 is a single-pass, multimode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of any type of optical signal across rotational interfaces.

The FO197 fiber optic rotary joint can be combined with our electrical and / or fluid slip rings, providing a single, compact package for optical signals, electrical power and fluid transfer.

The FORJ can be assembled with pigtail lengths tailored to the customer’s application or installed with connector bushings (ST or FC). Housing, mounting flange and drive features can also be customized to meet the customer’s requirements.
