HOW DO FIBER OPTIC ROTARY JOINTS WORK?
In automotive and electromechanical, a lot of rotations take place. There is a need for a device that will help support the transfer of signals and power from the rotating parts to the stationary parts. Do you know about slip rings? What about fiber optic rotary joints? Read below to know more and how they relate.To get more news about

Machines and devices don’t transfer power alone. Due to the advanced technology, there is an increasing demand for them to transfer data without loss, damage, or distortion. That is where the fiber optic rotary comes in handy. Do you know what it is?
What Is a Fiber Optic Rotary Joint
The fiber optic joint is to fulfill the essential requirement of connectivity. Just as the slip ring transfers power and signal from moving parts to stationary ones, the RF rotary joint passes signal and massive data across rotating parts without any loss, damage, or mix-up.
Now you understand why you should compare and relate it with slip rings. The joints are to facilitate the transfer of data just as the electro slip ring does to electrical signals. The significant part of RF rotary joints is that they pass both analog and digital signals.
Types of Fibre Optic Rotary Joints
There are different fiber optic manufacturers in the market. However, each makes the RF rotary joints according to set standards and customer specifications. There are two ways to classify joints. You can have active or passive or have single or multiple channels. Let’s look at the first one.
Passive and Active Types
It is like analyzing analog and digital signals. They are different, carry specific functions, and that is why we shall look at them separately:
Active rotary joints: Active rotary joints contain a light source at one end of the rotary and an interphase or detector on the other side. When you look at it this way, you find that most electronics are integral to the active unit of the RF rotary joints.
Most of the active joints are designed to transfer electronic signals of a rotating body without using a mechanical slip ring to avoid the challenges of wear, data loss and isolation, and ground loop problems. So can one say they are a perfect substitute for a slip ring? The answer is yes!
Passive rotary joints: They are for passing optical signals rather than electrical signals. They provide a continuous fiber-optic connection between stationary and rotating parts. It can be looked at to be like passing analog signals.
The good part here is that passive rotary joints can be converted into existing ones by adding appropriate electronic and optical devices. So, which is another way can you categorize the RF rotary joints?
