It is widely known that high-frequency slip rings and fiber optic slip rings are two rather specialized types of slip rings. In addition to being used independently, they are often integrated with electrical slip rings to form combined electrical-high-frequency and electro-optical slip rings. An electric-high-frequency integrated slip ring is used to transmit high-frequency signals and power, mainly in radar tracking systems, while an electro-optical integrated slip ring can transmit both optical signals and power simultaneously.

Due to the different characteristics of optical and high frequency signals, situations arise in certain specialized applications where it is necessary to transmit both signals within the same slip ring. So, under what circumstances can such integrated transmission be achieved? First, let’s examine the physical structures of both types of slip rings to see if it is possible to integrate fiber optic slip rings and high frequency slip rings into each other’s internal structures.

Starting with the fiber optic slip ring, it requires the placement of optical components inside the slip ring, so it cannot be hollow and therefore cannot integrate other slip rings inside. Turning to the high-frequency slip ring, in addition to performing the functions of traditional electrical slip rings, it can also transmit high-speed analog signals in the range of 500 MHz to more than 50 GHz.

When combining high-frequency (mid-frequency) and fiber signals within a single slip ring, traditional methods must still be used. The high-frequency signal module must be designed as a traditional electrical slip ring using a brush and copper ring contact and the external structure of a coaxial line. In addition, in order to integrate the fiber optic contact ring, it should be made with a hollow structure. Then this integrated signal module combining fiber optics and high frequency signals is integrated with the power ring module. JINPAT LPT000-02200-10180-01100-1660-1210-0202-0205-16 SI02-HF02 contact ring is a typical product that simultaneously integrates fiber optics and medium and high frequency signals.
