What is the term for the loss of power over a distance?
The power loss of signal over the distance is referred to as attenuation. It is also called packet data loss, which increases as the transmission distance increase. Signal strength decreases for coaxial cable as the length of cable increases. Coaxial cable. About the author.
What is latency in a network?
Latency is the delay in transmission of data from sender to receiver. The heavy workload on a network can increase the latency. Latency can be reduced by reducing the load on the network .
What is coaxial cable?
Coaxial cable is built from a single copper or copper-coated steel cable as the central core, which carries the high-frequency signal. A dielectric nonconductor encloses this wire, usually made of plastic, that maintains a constant distance between the middle conductor and the next layer.
How many gigahertz does a coaxial cable have?
Usually, a standard Coaxial cable can be pass frequencies up to 5 gigahertz. For higher frequencies to be transmitted, you require special coaxial cables. This range is also termed as Bandwidth of cable.
What is the purpose of coaxial wire?
A coaxial wire conducts a signal that goes across the middle copper wire as well as the metal shield. Both of these metal conductors produce a magnetic field. The nonconductors keep the signals from coming in contact with or canceling out each other. The nonconductors also preserve the signal from outside magnetic fields.
What is the insulator made of?
This insulator is covered with a metal shield made of aluminum, woven copper, or other metal. This eliminates outside electromagnetic interference. The last layer is a rubber wrapper that covers the whole configuration.
What is a coax cable?
Coaxial cable, or coax (pronounced / ˈkoʊ.æks /) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric ( insulating material); many coaxial cables also have a protective outer sheath or jacket. The term " coaxial " refers to the inner conductor and ...
When was coaxial cable invented?
Coaxial cable was used in the first (1858) and following transatlantic cable installations, but its theory wasn't described until 1880 by English physicist, engineer, and mathematician Oliver Heaviside, who patented the design in that year (British patent No. 1,407).
Can a coaxial cable cause interference?
A continuous current, even if small, along the imperfect shield of a coaxial cable can cause visible or audible interference. In CATV systems distributing analog signals the potential difference between the coaxial network and the electrical grounding system of a house can cause a visible "hum bar" in the picture.
What is the insulator used in a cable?
The properties of the dielectric insulator determine some of the electrical properties of the cable. A common choice is a solid polyethylene (PE) insulator , used in lower-loss cables.
What is PTFE used for?
Solid Teflon (PTFE) is also used as an insulator, and exclusively in plenum-rated cables. Some coaxial lines use air (or some other gas) and have spacers to keep the inner conductor from touching the shield. Many conventional coaxial cables use braided copper wire forming the shield.
What is the dielectric of coaxial cables?
Coaxial cables require an internal structure of an insulating (dielectric) material to maintain the spacing between the center conductor and shield. The dielectric losses increase in this order: Ideal dielectric (no loss), vacuum, air, polytetrafluoroethylene (PTFE), polyethylene foam, and solid polyethylene.
What are coaxial connectors?
Coaxial connectors are designed to maintain a coaxial form across the connection and have the same impedance as the attached cable . Connectors are usually plated with high-conductivity metals such as silver or tarnish-resistant gold. Due to the skin effect, the RF signal is only carried by the plating at higher frequencies and does not penetrate to the connector body. Silver however tarnishes quickly and the silver sulfide that is produced is poorly conductive, degrading connector performance, making silver a poor choice for this application.

Overview
Important parameters
Coaxial cable is a particular kind of transmission line, so the circuit models developed for general transmission lines are appropriate. See Telegrapher's equation.
In the following section, these symbols are used:
• Length of the cable, .
Applications
Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers to their antennas, computer network (e.g., Ethernet) connections, digital audio (S/PDIF), and distribution of cable television signals. One advantage of coaxial over other types of radio transmission line is that in an ideal coaxial cable the electromagnetic field carrying the signal exists only in the space between the inner and outer con…
Description
Coaxial cable conducts electrical signal using an inner conductor (usually a solid copper, stranded copper or copper plated steel wire) surrounded by an insulating layer and all enclosed by a shield, typically one to four layers of woven metallic braid and metallic tape. The cable is protected by an outer insulating jacket. Normally, the outside of the shield is kept at ground potential and a sig…
Construction
Coaxial cable design choices affect physical size, frequency performance, attenuation, power handling capabilities, flexibility, strength, and cost. The inner conductor might be solid or stranded; stranded is more flexible. To get better high-frequency performance, the inner conductor may be silver-plated. Copper-plated steel wire is often used as an inner conductor for cable used in the cable TV industry.
Signal propagation
Twin-lead transmission lines have the property that the electromagnetic wave propagating down the line extends into the space surrounding the parallel wires. These lines have low loss, but also have undesirable characteristics. They cannot be bent, tightly twisted, or otherwise shaped without changing their characteristic impedance, causing reflection of the signal back toward the source. They also cannot be buried or run along or attached to anything conductive, as the exten…
Connectors
The ends of coaxial cables usually terminate with connectors. Coaxial connectors are designed to maintain a coaxial form across the connection and have the same impedance as the attached cable. Connectors are usually plated with high-conductivity metals such as silver or tarnish-resistant gold. Due to the skin effect, the RF signal is only carried by the plating at higher frequencies an…
