Data cables are used to transfer information between systems such as servers, PCs and other hardware. There are three main types of data cables used for data transmission: twisted pair, coaxial and fiber optic cables. Many types of data cables are used in different environments. These Florida Data Cabling have different characteristics that make them identifiable.
Twisted pair cables are used in telephony and computer networks. Most wired networks are wired with an armored twisted pair cable. They are types of data cables with a cover to prevent signal degradation from other sources. The twisted pair gets its name from twisting the cables that cover all the wiring. The twist in the cables also helps protect data communication against signal degradation. Twisted pair cabling can expand just a little before the signal is damaged. The average length of a twisted pair cable before the degradation of the signal is 300 feet.
Twisted-pair cables, commonly used in homes such as Ethernet cables, are used to connect computer networks. The twisted pair cables consist of three to six twisted pair cables used to transmit signals. Satellite systems also use telephone cables, another form of unshielded twisted pair cable. Satellite television uses Ethernet cables for decoders equipped with networks of computer networks so subscribers can see the details of the decoder and make changes to the remote programming. Telephone cables are often required when requesting premium pay-per-view content. These data will be sent to the provider for billing during the nightly data download.
Coaxial cables are used in old computer networks. The coaxial cable has been replaced as standard for computer networks with shielded twisted pair cable. The coaxial cable is a large round table with an internal core that transmits the data. The core is surrounded by an insulator and a shield to protect the data communication signal. These parts are surrounded by the housing. The coaxial wiring requires a special connector called a BNC connector. These connectors are used to buy network cards for computers that connect this type of network.
The coaxial cables consist of a central copper conductor surrounded by several shielding layers. This is the cable that connects a satellite dish to a decoder. These cables are highly resistant to electromagnetic and radio interference, making them ideal for sending sensitive low-level digital signals to satellite decoders.
Fiber optic cables are the preferred option for fast data connections. Fiber is used by cable and telephone companies to make fast connections to the Internet. Optical fibers use light and glass as mechanisms for data communication. Fiber optic cables are very fragile due to the glass parts of the cable. The fiber optic cables are lightweight and do not have the problems of signal degradation that occur with the other two data cables. However, fiber optic networks are more expensive and require special network cards and hardware to transmit the signal.
Fiber optic cables are commonly used to send digital audio from satellite set-top boxes to home theater receivers. Optical fibers consist of glass or plastic threads, which transport the transmitted light as a signal carrier. This is a noiseless data system that is inexpensive to use in household and commercial equipment. Fiber optic cables allow the use of “surround sound” with speakers from satellite decoders.
Cable pairs, fiber optic cables, and coaxial cables are transmission media that can be used to transmit a signal from point to point. Although all three types of cable are common in most households, there are differences in their functions with respect to the satellite television service.
