Technical Note
Many types of video coax. What’re the differences and how select?
In brief, there are three of essential factors:
(1) center conductor, (2) insulation, and (3) shield. Eachfactor has its advantage and disadvantage as described below:
| 1 | Center Conductor | Solid conductor | Single solid metal core, low signal loss, ideal for long-distance or high-frequency transmission. |
|---|---|---|---|
| Stranded conductor | Multiple thin strands twisted together, offers flexibility and resistance to bending, commonly used for patch cords and mobile applications. | ||
| Compact strand conductor | Multiple fine metal wires tightly bundled, denser than regular stranded conductors, which achieving advantages from both solid and stranded. It enhances low signal loss and flexibility, ideal for 12G-SDI mobile applications. | ||
| 2 | Insulation | Includes “Solid”, “Foamed”, and “Highly-foamed” types. Foamed and highly-foamed insulation would perform better attenuation, compared to the solid type thus they are often selected for hi-def video. However, since foamed and high-foamed insulation contain the air physically, they are weak to external pressure. You should pay attention to where and how the cables are installed. | |
| 3 | Shield | We have “Braided” and “Braided with aluminum foil” type. Braided shields include single, double, or triple layers as well as bare copper or tinned copper. Braided with aluminum foil offers perfect screening, but they are not suitable for repeated bending and mobile applications due to the foil’s lack of strength. In that case, it’s better to choose “Braided”. | |
What is Propagation Delay?
Propagation delay refers to the time required for a signal to be transmitted from one end of connection to another. In the case of cable transmission, this greatly depends on the materials and construction of the actual cable, and large differences in delay can cause transmission errors if they exceed the receiver delay tolerance. The following table shows the differences in coaxial cable propagation delay time relative to the insulation type.
| Insulation | Propagation Delay |
|---|---|
| Solid PE | 5.0 ns/m |
| Foamed PE | 4.2 ns/m |
| Highly-Foamed PE | 3.7 ns/m |

* The above values are distances when cable loss reaches a typical attenuation specified by SMPTE standard at 1/2 clock frequency.
* These values are not equivalent to actual transmission distances, which depends on the equalized distance of receiver.
* Please check with vendor of receiver for equalized distance and reference cable to calculate actual transmission distance.
