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.

Slip Ring Maintenance

The maintenance requirements of slip rings are highly dependent upon application, especially the frequency of rotations and physical environment. For example, a crane only needs to turn occasionally, even when it’s in operation. The entire crane may therefore reach the end of its service life before slip rings require their much scheduled … Read More...

How Long Do Slip Rings Last?

Slip Rings transfer power or signals across a rotating surface. They are made from electrically conductive material and work in conjunction with brushes. As the slip ring rotates the brushes come in contact with the ring producing power or signals. Slip Ring Housings The ring and brushes are housed within a unit designed to withstand harsh … Read More...

How Much Do Slip Rings Used in Wind Turbines Typically Cost?

A wind turbine converts kinetic energy into electrical energy by using the wind to turn a set of rotor blades around a central axis. This design requires a slip ring, which transmits an electrical current from a stationary to a rotating structure. The slip rings used in wind turbines are typically customized for each turbine, so a slip ring’s cost … Read More...
