Fiber Optic Rotary Joints

FO282

Single Channel FORJ

The FO282 (single-pass singlemode) is passive and bidirectional, and maintains the benefits of fiber optics (such as high bandwidth and EMI immunity) in systems with a rotational interface.

This cost efficient FORJ model is designed for applications having moderate demands for optical performance and life. Due to the lens-less design, it can operate at any wavelength supported by the fiber used in the assembly.

This FORJ can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.
