There are three common types of cable media that can be used to connect devices to a network and they are coaxial cable, twisted-pair cable, and fiber-optic cable.
Share on Facebook There are three general classes of media types: Coaxial cable had suffered waning popularity, but is making a bit of a comeback with cable modem solutions. There are two types of fiber-optic cable: Twisted pair is the most common type of computer network cabling.
Twisted pair can be classified according to the value of the intrinsic impedance of the wire, and whether it is shielded or unshielded. Unshielded twisted pair, with an intrinsic impedance of ohms, is the most common type of computer network cabling used today.
Coaxial Cable A coaxial cable has a central conductor. Coaxial cable uses a single conductor in the middle of a cable. The central conductor is surrounded by an insulator called the dielectric.
A conductive shield is put around the dielectric. This shield acts as the second conductor for the circuit as well serves to protect the inner conductor from interference.
Coaxial cable for local area network LAN connections is obsolete. Coaxial cable is being used in some cases for delivering the last mile of service.
Unshielded twisted pair cabling, or UTP cabling, is the most common type of network cabling. It consists of four twisted pairs of wire, each with a different number of twists per foot, all encased on one sheath. UTP cabling is graded according to category. Category 3 and 4 were replaced by Category 5 cabling by the year Category 5 is recommended for running Ethernet at speeds of Mbps.
Category 5e, was introduced to run gigabit Ethernet or BaseT networks. Category 6 and Category 6a have since been introduced to give better performance at higher speeds.
UTP cabling has an intrinsic impedance of ohms. There are two types of shielded twisted pair wiring. In the s and s shielded twisted pair was promoted as the best wire type for Token Ring networks. This had an intrinsic impedance of ohms. A new wiring trend is to use ohm shielded twisted pair.
The shielding reduces noise and increases the performance of the cable. These are sometimes called foiled twisted pair, or FTP not to be confused with file transfer protocol or sometimes called screened twisted pair, or ScTP.
These types of cables are compatible with normal UTP. Multi Mode Fiber Optic Cable Fiber optic cable is sometimes called wave guide or light guide because it guides the light waves along the length of the cable. Multi mode fiber is used for short cable runs, usually 1.
Single mode fiber optic cable can operate over much longer distances. Because the fiber only allows one mode of light to propagate, light pulses put on the fiber keep their shape much longer.
This allows the light pulses to travel much further without interfering with other pulses. Single mode fibre is recommended for cable runs in excess of 1.This tutorial explains network cable types and specifications in details.
Learn what type of network cable is used in what type of computer network. Understanding network cable type and specification will help you in selecting the right cable type for your network.
Comparing Media Types. Presented in Table are comparisons of the features of the common network media.
This chart provides an overview of various media that you can use as a reference. The medium is possibly the single most important long-term investment made in a network. Network media is the actual path over which an electrical signal travels as it moves from one component to another.
I want to explain the common types of network media, including twisted-pair cable, coaxial cable, fiber-optic cable. This chapter describes the common types of network media, including twisted-pair cable, coaxial cable, fiber-optic cable, and wireless.
Twisted-Pair Cable Twisted-pair cable is a type of cabling that is used for telephone communications and most modern Ethernet networks. Describe the primary types and uses of wireless media Network Media Types Network media is the actual path over which an electrical signal travels as it moves from one component to another.
This chapter describes the common types of network media. There are so many different types of computer networks in existence, it can be hard to understand the differences between them, particularly the ones with very similar-sounding names.
