In physics, attenuation or, in some contexts, extinction is the gradual loss of flux intensity through a medium.
Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.
A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly.
Category 3 cable, commonly known as or station wire, and less commonly known as VG or voice-grade (as, for example, in 100BaseVG), is an unshielded twisted pair (UTP) cable used in telephone wiring.
Category 5 cable, commonly referred to as Cat 5, is a twisted pair cable for computer networks.
Category 6 cable, commonly referred to as Cat 6, is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.
The characteristic impedance or surge impedance (usually written Z0) of a uniform transmission line is the ratio of the amplitudes of voltage and current of a single wave propagating along the line; that is, a wave travelling in one direction in the absence of reflections in the other direction.
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources.
A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made.
Copper has been used in electrical wiring since the invention of the electromagnet and the telegraph in the 1820s.
The decibel (symbol: dB) is a unit of measurement used to express the ratio of one value of a physical property to another on a logarithmic scale.
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied.
The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor.
IEEE 802.3 is a working group and a collection of Institute of Electrical and Electronics Engineers (IEEE) standards produced by the working group defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.
In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB).
The International Organization for Standardization (ISO) is an international standard-setting body composed of representatives from various national standards organizations.
International standard ISO/IEC 11801 Information technology — Generic cabling for customer premises specifies general-purpose telecommunication cabling systems (structured cabling) that are suitable for a wide range of applications (analog and ISDN telephony, various data communication standards, building control systems, factory automation).
A nanosecond (ns) is an SI unit of time equal to one thousand-millionth of a second (or one billionth of a second), that is, 1/1,000,000,000 of a second, or 10 seconds.
Power over Ethernet or PoE describes any of several standard or ad-hoc systems which pass electric power along with data on twisted pair Ethernet cabling.
A split pair is a wiring error where two wires of a twisted pair are instead connected using two wires from different pairs, potentially creating interference.
The Telecommunications Industry Association (TIA) is accredited by the American National Standards Institute (ANSI) to develop voluntary, consensus-based industry standards for a wide variety of Information and Communication Technologies (ICT) products, and currently represents nearly 400 companies.
ANSI/TIA-568 is a set of telecommunications standards from the Telecommunications Industry Association (TIA).
Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility.
Voice over Internet Protocol (also voice over IP, VoIP or IP telephony) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.
