Are they still relevant in today's technology?
Coaxial is the type of cable that has been a staple in the realm of telecommunications for decades, but as technology continues to evolve, the question arises: Are coaxial cables still a relevant and prevalent form of connectivity in today's world? In this comprehensive exploration, we delve into the intricacies of coaxial cables - from their design and applications to the types, connectors, and advantages they offer that are still being used.
What is a Coaxial Cable and How Does it Work?
While we know what is a coax cable. Let's see it built. It incorporates a central conductor, typically made of copper or copper mixed with steel, ensconced by a non-conductive insulator, a metallic shield made up of bare copper, and an outer insulative sheath. The inner conductor holds the information, while the surrounding layers serve to protect the information from external interference. This design ensures high-quality, reliable transfer of data or signals over varying distances. In essence, coaxial cables work by carrying data in the form of electromagnetic waves between conductors.
Understanding the Coaxial Cables Design and Functions
Coaxial cables are a type of electrical cable that consists of an inner conductor, an insulating layer, a metallic shield, and an outer insulating layer, all arranged concentrically. The central conductor carries the signal, while the metallic shield ensures that the signal remains unaffected by external electromagnetic interference.
Coax cables typically have two types of shielding: Foil and Braid.
Foil shielding uses a thin layer of aluminum, providing 100% coverage of the cable. It is usually attached to a carrier such as polyester to add strength and ruggedness.
Braid shielding involves braided bare or tinned copper wires, which can achieve up to 95% coverage. It is terminated in the field by crimping or clamping and occasionally soldered.
The shield of a coax cable serves four basic purposes: to keep the desired electrical currents inside, keep the undesired currents outside, provide a more uniform inner surface to the coaxial conductor, and reduce the effects of noise induced in neighboring cables or bundles of wires.
How are Coaxial Cables Used in Different Applications?
