Security Systems: Coaxial cables are used in security systems such as CCTV cameras and video surveillance systems. Industrial Communications: In various industries, coaxial cables serve as a means for data transmission and remote control.

Advantages of Coaxial Cable:

Resistance to Interference: Due to its dual shield and insulation, coaxial cable is resistant to electromagnetic interference in the environment.
Signal Quality: Since signals are transmitted precisely and without interference inside the cable, their quality is preserved.
High Frequencies: These cables are particularly suitable for transmitting high frequencies and are used for digital and analog data transmission.
Recent and Future Developments: With advances in technology, coaxial cables have also improved. Advanced versions capable of transmitting higher data rates and frequencies have been developed. Additionally, new technologies such as fiber optic coaxial cables (FOC) are used to increase data speed and enhance signal quality. In the future, coaxial cables are expected to play a key role in 5G networks and the Internet of Things (IoT). With the growing need for speed and stability, more advanced technologies in coaxial cable design and manufacturing will be used.
Hybrid and Complementary Technologies: Along with improvements in coaxial cables themselves, hybrid technologies play an important role in enhancing their performance. For example, combining coaxial cables with signal boosting technologies allows weak signals to be transmitted over longer distances, improving communication quality.
Network Expansion: In the future, the demand for faster and more stable communication will grow. With the increase in connected devices and the need for large-scale data transmission, coaxial cables will remain a reliable solution in communication systems.
Challenges in Combating Interference: One of the key challenges in coaxial cable usage is dealing with electromagnetic interference. With the development of new technologies and resistant materials, efforts are ongoing to improve cable performance against various interferences.
Innovations: Researchers and engineers are continuously working on new innovations for coaxial cables. These include enhancing data transfer speed, reducing signal loss over long distances, increasing bandwidth, and improving resistance to interference.

Conclusion:

Coaxial cable is a key communication technology for transmitting data and electrical signals across various industries and applications. Thanks to its protective structure, it resists electromagnetic interference and maintains signal quality. With modern technologies and the growing demand in communications, coaxial cables are expected to play an increasingly vital role in improving communication quality and speed. These cables are widely used in TV and radio communications, computer networks, security systems, and industrial applications. Given their advantages in high-quality signal transmission and interference resistance, they remain one of the primary solutions for data transmission in the modern world.
