What is the proper type of coaxial cable used in video systems?

The proper type of coaxial cable used in video systems is RG-59U. This type of cable is specifically designed for video transmission and is often used for connecting cameras to monitors or recording devices. RG-59U has a characteristic impedance of 75 ohms, making it suitable for high-frequency video signals, which ensures minimal signal loss and degradation over distances.

While aluminum and copper braids can be components in different types of cables, they do not specifically refer to video transmission capabilities. Fiber optic cables, on the other hand, are designed for transmitting data as light, which is not applicable for traditional video systems that typically rely on coaxial cables like RG-59U. Thus, RG-59U stands out as the appropriate choice for video systems due to its specifications and intended use.
