Understanding Coaxial Cable

What is Coaxial Cable?
Coaxial cables are electrical transmission lines used to pass high radio frequency (RF) signals from one point to another with low signal loss.
They have many applications, including phone lines, cable TV, internet, cell boosters, and more. Coax cables come in many sizes and lengths, each designed for specific uses.

Ucoax provides a wide range of standardized and customized Micro Coaxial Cables AWG 36-46 solutions in high-frequency & high-speed applications. These solutions ensure the reliable transmission of signals, data and power in highly demanding applications.

Our selection of cable assemblies range from simple jumpers to power and high-speed data cables to complex harnesses. They are used in a wide variety of applications and industries to interconnect components, sub-systems, and equipments.

Before we get into how coax cables work, you need to know how they`re constructed.

As you can see from the above image, there are four main parts to a coax cable:

Center Conductor/Core

Dielectric Insulator
Shield(s)
Jacket (Rubber Wrapper)
At the core, coaxial cables consist of a single copper or copper-coated steel wire. It`s what carries the RF signals. A dielectric insulator, often made of plastic, surrounds the wire. It keeps a constant distance between the center conductor and the next layer.

The metal shield, made of woven copper, aluminum, or other metals, wraps around the insulator. It cancels outside electromagnetic interference. Some coaxial cables are constructed with multiple shields for extra protection. The final layer is a jacket that protects the whole configuration. Its rating (more on this later) lets you know where the cable can be installed.

Outdoor-rated cables need extra insulation and special jackets to protect the wires from sun and moisture.

What Is Thunderbolt 3?

Thunderbolt 3 is the upcoming version of the Thunderbolt interface. The specifications have been released, but the interface itself is not available on PCs yet. Thunderbolt 3 lets you transfer data at up to 40Gbps. That's twice as fast as the 20Gbps throughput speed of Thunderbolt 2, and four times as fast as the 10Gbps of USB-C and the original Thunderbolt interface. Thunderbolt 3 lets you connect speedy hard drives, various displays (including 4K and 5K resolutions), and other peripherals, like PCIe Gen 3 expansion cages, to your desktop or laptop.

A plug and play safe solution Compatible with any Mac, PC, iPad, Chromebook, Surface tablet or ny other device, display, or power supply with Thunderbolt 3, Thunderbolt 4, USB-C, or USB4 port.

How Do Coaxial Cables Work?
Coaxial cables transmit signals through the center wire. To ensure a quality signal travels the length of the cable a metal shield is needed. Both components receive a current simultaneously, generating a magnetic field. This allows the signal to remain intact and not bleed out like it would without the shield.

The metal shield also helps protect the signal from electromagnetic interference. Thus, coax can be placed near other electronic equipment without any issues.

For optimal performance, the distance between the core and shield must be consistent throughout. The dielectric insulator makes that happen. It also prevents the two signals from coming in contact and canceling each other.

All components are further insulated and protected from damage by the outer jacket.

As a result, RF signals can be carried over long distances with little interference or loss. Depending on your application, the signal is then converted into images, audio, WiFi, or amplified cell reception.
