Problems solved by technology
However, electric slip rings have the following disadvantages: (1) low bandwidth, unable to complete high-speed transmission of large-capacity data; (2) poor anti-electromagnetic interference ability, easy to be interfered by external signals, resulting in signal distortion; (3) electrical signals pass through electric When the slip ring is used, there is a current between the brush and the slip ring, which may easily cause a short circuit in the system and cause communication interruption
For multi-channel optical signals, multi-channel optical fiber rotary connectors can be used, but as the number of channels increases, the volume of the device will increase; single-channel optical fiber rotary connectors can also be used to expand the wavelength in combination with wavelength division multiplexing technology. However, the use of multiple wavelength division multiplexers increases the cost of the device
