Transmission line or networking cables are used to connect systems that require the transmission of signals from one point to another. There are different types of cable, which are designed differently to serve different purposes. Choosing the correct type of cables for a network or system will mean more efficiency and wrongly chosen cables will mean poor transmission and significant loss of signal resulting in poor results. Different factors like surroundings, distance, bandwidth, and capacity play an important role in choosing the suitable type of cable.
Coaxial cables transmit signals in the transverse electromagnetic TEM mode. Its application varies from data, video, and voice communication and its wide range of utilities have made these cables a familiar sight for most people.
Designing of a cable mainly dictates its advantages and limitations. Coaxial cables are specifically designed to minimize external interference as all the layers in the wire wrapped over each other share a common axis. A coaxial cable can have a varied thickness of conductor, shielding and protective jacket depending upon the intended application. Good quality coaxial cables are fire resistant and waterproof.
Advantages
Lowest interference, better performance – The coaxial cable is less susceptible to EMI or RFI interference in comparison to twisted pair. The shielding functions to prevent any interference from surrounding during the rapid signal transmission so the quality of the signal is not compromised. This means that coaxial cables offer higher transmission rates, yield the best performance for shorter distance transmissions.
Wider Frequency Spectrum – Coaxial cables are capable of transmitting a much larger frequency spectrum in comparison to the twisted pair.
Strong Insulation – Coaxial cables are heavily insulated which reduced the problem of signal leakage and in an ideal system there should be no leakage at all.
Low-cost easy installation – Coaxial cables are less costly than fiber optic. They are also very easy to install as the process is less complicated, the wires are bendable and expandable.
Durability – Coaxial Cables are lightweight yet more durable and long-lasting, thus fewer repairs are required. Repairs, when required, cost less due to the cheap price. This decreases the chances of experiencing any downtime and also reduces the expenses of maintenance.
Disadvantages
Leakage at point of connection – Coaxial cables experience signal leakage at the point of connection. The most commonly used connector for appliances like tv sets is F-connector.
Poor long-distance transmission – Coaxial Cables are not suitable for long-distance transmissions due to significant data loss over the extended distance.
Security – Unauthorized access to signals is an issue as the cables can be easily tapped and it is very easy to install a splitter or T-Joint.
Application
Due to the best transmission for shorter distance but signal loss for longer distance, coaxial cables are an ideal candidate for house and office use. Coaxial cables are used to connect the transmitter to an antenna and networking system within the premises, like CCTV camera connections, internet, television, and telephone connections. Most frequently coaxial cables are used by telecommunication service providers for example cable tv and internet connection.
