How Do Fiber Optic Rotary Joints Work?

fiber optic rotary joints

In this modern world, the term fiber optic is pretty common.  From telecommunications to video, industrial, and military applications, fiber optics are everywhere.  They work by using light to carry high volumes of data faster and with more capacity than could previously be done with copper wire.

When a Fiber Optic Cable Has to Rotate

What happens when a Fiber Optic signal needs to be delivered and stay connected while the application is also rotating?

This question fueled the development of the fiber optic rotary joint, or FORJ. The FORJ is a precision component that utilizes a precise lens and prisms to funnel and align the light, and the data/signals the light carries.  The FORJ component can carry the data over an air gap while the component is rotating.  In short, the FORJ preserves the integrity of the data so that nothing is lost in the transfer.

Fiber Optic Rotary Joints are available in many configurations.   The amount of data to be transferred and the distance the light needs to travel between the transmission and the receiving points will dictate which FORJ is right for your project.

Four Common Problems With Fiber Optic Rotary Joints

A slip ring is an electromechanical device that transmits electrical current between a stationary and rotating structure. A Fiber Optic Rotary Joint (FORJ) is the contactless optical equivalent of a slip ring, since it transmits an uninterrupted optical signal as it rotates. FORJs are widely used in many applications, including remotely operated … Read More...
