Difference Between Optical Fiber Slip Ring and Electrical Slip Ring

Fiber optical rotary joint and electrical slip ring, two kinds of rotary connectors, have the same function in essence, both of which can solve the problem of wire winding during the 360°

rotation of the device.Next, we will analyze the differences between optical fiber slip ring and electrical slip ring in detail.


1. The transmitted signal is different

The electrical slip ring realizes the electrical signal connection between the rotating end and the fixed end through mechanical contacts, which has a wide range of applications and mature

technology.The optical fiber slip ring is a kind of precise optical transmission device, which is the hinge to realize the continuous transmission of optical signals between the rotating end and the

fixed end.

2. the carrier of the transmission signal is different

The traditional electrical slip ring and optical fiber slip ring are the slip rings that use two absolutely different materials as the signal transmission carrier.The electrical slip ring uses copper as

the carrier for signal and energy transmission, while the transmission carrier of the optical fiber slip ring is silicon dioxide.

3. Volume is different

The structure of the fiber optic slip ring is very compact, unlike other slip rings that sometimes must be up to one meter in diameter.The fiber optic slip ring has a relatively small volume and light weight. It is   also very time-saving and

labor-saving to assemble.Many applications in the field that must transmit large signals choose the fiber optic slip ring as the core component of the rotating structure.

4. The reliability of signal transmission is different

The signal transmission between the rotating end and the fixed end of the optical fiber slip ring is non-contact, there is no wear problem, and it has the advantages of long service life and maintenance free.   In addition, one optical fiber slip ring channel can simultaneously transmit analog signals   and digital signals, which has a larger amount of data transmission and higher channel utilization than electrical slip rings.



Due to the respective characteristics of electrical slip rings and optical fiber rotary slip rings, people will choose different slip rings according to different needs and application scenarios. However, electrical slip rings and optical fiber slip rings also have their own shortcomings. People began to pay attention to the slip rings integrated with electrical slip ring and optical fiber slip ring, which can transmit energy and different signals at the same time, so that they can adapt to more complex environments. As a veteran slip ring manufacturer, JINPAT Electronics is very good at the   development of various types of electrical slip rings, optical fiber slip rings and their integrated products. JINPAT Electronics has won a lot of praise for providing customers with a lot of   personalized custom slip rings.
