RG-58 is a well - known coaxial cable that has been widely used in various communication and electronic applications. As a supplier of RG - 58, I often receive inquiries about its capabilities and potential uses. One question that has come up recently is whether RG - 58 can be used for infrared signal transmission. In this blog, we will explore this topic in detail, considering the characteristics of RG - 58 and the nature of infrared signals.
Understanding RG - 58
RG - 58 is a type of coaxial cable that consists of a central conductor, an insulating layer, a metallic shield, and an outer jacket. It is typically used for radio frequency (RF) applications, such as in amateur radio, Ethernet networks (in the early days of 10BASE2 Ethernet), and other low - power RF systems. The cable has a characteristic impedance of 50 ohms, which makes it suitable for transmitting RF signals efficiently.
The central conductor of RG - 58 is usually made of copper or copper - clad steel, which provides good electrical conductivity. The insulating layer, often made of polyethylene, helps to prevent signal leakage and interference. The metallic shield, usually a braided copper or aluminum layer, further protects the signal from external electromagnetic interference.
Characteristics of Infrared Signals
Infrared (IR) signals are part of the electromagnetic spectrum, with wavelengths ranging from about 700 nanometers to 1 millimeter. Infrared signals are commonly used for remote control systems, data transmission over short distances, and in some security and surveillance applications.
Infrared signals are typically transmitted through the air or through optical fibers. They are sensitive to obstacles, such as walls and other solid objects, which can block or absorb the signals. Unlike RF signals, which can travel through various media and around obstacles to some extent, infrared signals require a clear line - of - sight for effective transmission.
Can RG - 58 be Used for Infrared Signal Transmission?
The short answer is no, RG - 58 is not suitable for infrared signal transmission. There are several reasons for this:
1. Signal Propagation Mechanism
RG - 58 is designed to transmit electrical signals, specifically RF signals. The cable works by guiding the electrical current through the central conductor and the return path through the shield. Infrared signals, on the other hand, are electromagnetic waves that propagate through the air or optical media. The physical structure of RG - 58 is not designed to support the propagation of infrared waves.
2. Frequency Range
The frequency range of RG - 58 is optimized for RF signals, typically in the range of a few megahertz to several gigahertz. Infrared signals have much higher frequencies, in the range of hundreds of terahertz. The electrical properties of RG - 58, such as its capacitance, inductance, and impedance, are not suitable for handling such high - frequency infrared signals.
3. Material Compatibility
The materials used in RG - 58, such as the polyethylene insulation and the metallic shield, are not transparent to infrared light. These materials would absorb or reflect the infrared signals, preventing them from being transmitted effectively through the cable.
Alternative Solutions for Infrared Signal Transmission
If you need to transmit infrared signals, there are several alternative solutions available:
1. Infrared Emitters and Receivers
These are dedicated devices that can send and receive infrared signals. They are commonly used in remote control systems, where the infrared emitter in the remote control sends a signal to the infrared receiver in the device being controlled.
2. Optical Fibers
Optical fibers are made of materials that are transparent to infrared light, such as glass or plastic. They can be used to transmit infrared signals over long distances with low loss. Optical fibers are widely used in telecommunications and data transmission applications.

Conclusion
In conclusion, RG - 58 is not suitable for infrared signal transmission due to its design for electrical RF signal propagation, its frequency range limitations, and material incompatibility with infrared light. However, there are other solutions available for infrared signal transmission, such as infrared emitters and receivers and optical fibers.
