2. High-Quality Cables Help in Better Transmission of Signals There are many types of cables that are used for transmission of signals. Signals need to be transmitted for passing information from one source to another. This information can be in the form of different types of signals. Mobile phones transmit signals. Satellites receive and transmit signals over a wide distance. These signals are then transmitted using cables. The signals to your TV are radio frequency signals. These are best transmitted through an RF coaxial cable to your TV from the antenna that receives the signals from the satellite. Understanding What a Coaxial Cable Is The typical characteristics of coaxial cable are to transmit high-frequency electrical signals without suffering much loss during transmission. The coaxial cable is named so because two cables are sharing the same axis. There is an inner conducting cable that is surrounded by an insulating layer that is tubular in shape. Over this layer, there is another conducting layer over which there is usually another insulating jacket. The main advantage of such a cable is that the electrical and magnetic fields of the cable are contained inside the cable itself. The signals that are transmitted through the cable are hardly affected by magnetic or electrical fields outside. A coaxial cable has an outer layer that is normally resistant to chemicals, UV radiations, and fire. Coaxial cables are usually connected using an RF connector which has a pin that connects to the device and a threaded piece of metal that can secure the connection. Applications Of Coaxial Cables There are many applications of the different RF coaxial cable types used in different places. The most common use of this can be seen in your homes. The cable that connects your TV antenna to the TV or other devices is a coaxial cable. You will also be able to see the typical connector on these cables. These cables are also used in broadband internet connections. Radio transmitters are also connected using this cable. Strengthen the Fiber Optic Signals When signals have to travel a great distance, they need to be strengthened. As they cross distances they will lose their strength and the receivers will not be able to receive the signals. A fiber optic repeater helps to receive the signals and transmit it again so that the signals travel more distance. This helps to extend the distance traveled by the signal. This type of repeater will convert an optical signal into an electrical signal and transmit it. There are optical repeaters and amplifiers. The difference is that the amplifier only strengthens the signal without converting it. When the distance is more this will not be enough. This is where fiber optical repeaters help. Because they convert and send the signals as electrical signals, they are also called optical regenerators. The loss in fiber optic cables can happen due to optical fiber loss or dispersion. This is why repeaters are required to be placed at particular distances so that the signals can travel for a longer distance. Fiber optic repeaters and generators work by receiving the attenuated optical signals, convert them into electrical signals for processing. Once the processing is done, it is reconverted and transmitted as optical signals again. This is what allows the signals to travel a long distance. The quality of the repeater is crucial to the strengthening and transmission of the signals over long distances.
