Fiber Optic Rotary Joints

FO286

Single Channel FORJ

The FO286 (single-pass, multimode) is passive and bidirectional, and allows the transfer of optical signals across rotational interfaces.

With a body diameter of only 9.5 mm and length 19 mm the FO286 unit is ideally suited to applications where size and weight are critical issues. An extremely cost effective solution for high data rate signals, it also offers other benefits of fiber optics, including low spark hazard and immunity to electromagnetic interference.

The FO286 can be combined with our electrical and fluid slip rings, and with our entire line of video and data multiplexers to provide a complete solution.
