Why does High-end Equipment Use Fiber Optic Slip Rings?

With the continuous development of science and technology, more and more equipment is intelligent, and the product technology of slip rings has also been greatly improved. The slip ring can transmit high-frequency signals, as well as video signals, ordinary signals, and currents at the same time, and supports 1080P, 1080I, and other HD-SDI high-definition turntables.

Optical fiber collector ring is a unique type among all collector rings. It transmits optical signals with a wavelength range of 650nm~1650nm. Its wire can choose single-mode or multi-mode optical fiber. A wavelength division multiplexer is used inside the optical fiber slip ring to realize one-to-many optical signal output, but this product is rare in the market and is almost in the laboratory stage.

Optical fiber can be divided into single-mode optical fiber and multi-mode optical fiber. Fiber optic slip rings must be used to transmit rotating optical signals between two optical fibers. The manufacture of single-mode optical fiber slip rings is relatively simple, while the manufacture and use of multimode optical fibers is very complicated, requiring the combination of multiple lenses.

Fiber optic slip rings are the best choice for transmitting optical signals in two rotating structures. Optical fiber slip rings are widely used, small in size, light in weight, and easy to assemble and install. In many occasions where fast signal transmission is required, optical fiber slip rings are used as connecting parts of rotating structures

But why does High-end Equipment Use Fiber Optic Slip Rings Instead of Standard Slip Rings?

First, I reckon it can transmit single or multi-channel fiber optic signal; Its connector: FC、SC、ST、SMA, or LC (PC /APC), etc. optional; Small size, 100-way electric slip ring, and the length will reach more than 330mm, the outer diameter will be more than 60mm； It even Can be combined to transmit power, control signal, a micropower signal of computer automotive control. and It can be combined with the traditional electric slip ring to transmit power and high-speed data;

Non-contact, no friction, long working life, >100 million revolutions (2-3 million revolutions for signal channel model); This is another important trait.

So, I think this is the cause all customers choose it.
