Signal cables Signal cables A bridge tap is most often a wire that is hanging off a pair of lines in the Public Telephone Switched Network. This line is usually an old tap line to a business or home. Bridge taps create a reflection point for high frequency waves on the line creating problems for DSL use on that line. ...more on Wikipedia about "Bridge tap"
Category 1 cable is a grade of UTP cabling defined in the EIA/ TIA-568B standard. Category 1 cable was designed for telephone communications. ...more on Wikipedia about "Category 1 cable"
Category 2 cable, or simply Cat 2, is grade of unshielded twisted pair cabling described by the EIA/ TIA-568B standard. Category 2 cabling is capable of transmitting data at up to 4 Mbps. It is no longer commonly used. ...more on Wikipedia about "Category 2 cable"
Category 3 cable, commonly known as Cat-3, is an unshielded twisted pair (UTP) cable designed to reliably carry data up to 10 Mbit/s, with a possible bandwidth of 16 MHz. It is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance and the Telecommunications Industry Association. Category 3 was a popular cabling format among computer network administrators in the early 1990s, but has since been almost entirely replaced by the very similar Cat-5 standard, which offers higher top speeds. ...more on Wikipedia about "Category 3 cable"
Category 5 cable, commonly known as Cat 5, is an unshielded twisted pair type cable designed for high signal integrity. The actual standard defines specific electrical properties of the wire, but it is most commonly known as being rated for its Ethernet capability of 100 Mbit/s. Its specific standard designation is EIA/ TIA-568. Cat 5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cable. The twisting of the cable reduces electrical interference and crosstalk. Another important characteristic is that the wires are insulated with a plastic ( FEP) that has low dispersion, that is, the dielectric constant of the plastic does not depend greatly on frequency. Special attention also has to be paid to minimizing impedance mismatches at connection points. ...more on Wikipedia about "Category 5 cable"
Cat 6 - Category - 6, (ANSI/TIA/EIA-568-B.2-1) A cable standard for Gigabit Ethernet and other interconnect that is backward compatible with Category 5 cable, Cat-5e and Cat-3. Cat-6 features more stringent specifications for crosstalk and system noise. The cable standard is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T (Gigabit Ethernet) connections. ...more on Wikipedia about "Category 6 cable"
Category 7 cable (CAT7), ( ISO/ IEC 11801:2002 category 7/class F), is a cable standard for Ultra Fast Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional CAT5 and CAT6 Ethernet cable. CAT7 features even more stringent specifications for crosstalk and system noise than CAT6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole. ...more on Wikipedia about "Category 7 cable"
Coaxial cable is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, and usually surrounded by a final insulating layer. ...more on Wikipedia about "Coaxial cable"
Ladder line or window line is a type of transmission line similar to twin-lead for balanced connection of antennas. Ladder line is constructed as a pair of evenly spaced wires with supportive plastic webbing holding the wires apart. The plastic webbing has windows cut in it to reduce its dielectric effect and reduce loss in the transmission line. The alternating webbing and windows gives ladder line is characteristic look and name. ...more on Wikipedia about "Ladder line"
A microstrip is a thin, flat electrical conductor separated from a ground plane by a layer of insulation or an air gap. Microstrips are used in printed circuit designs where high frequency signals need to be routed from one part of the assembly to another with high efficiency and minimal signal loss due to radiation. They are of a class of electrical conductors called transmission lines, having specific electrical properties that are determined by conductor width and resistivity, spacing from the ground plane, and dielectric properties of the insulating layer. A microstrip transmission line is similar to a stripline, except that the stripline is sandwiched between two ground planes and respective insulating layers. ...more on Wikipedia about "Microstrip"
An optical fiber (or fibre) is a transparent thin fiber, usually made of glass or plastic, for transmitting light. Fiber optics is the branch of science and engineering concerned with such optical fibers. ...more on Wikipedia about "Optical fiber"
In contrast to overhead powerline an overhead cable is an separate cable, usually for the transmission of information, laid on pylons that are sometimes also used for the supply of electric power. Overhead telephone and cable TV lines are common in North America. Elsewhere, overhead cables are laid mainly for telephone connections of remote buildings and temporary mechanisms, as for example building sites. ...more on Wikipedia about "Overhead cable"
RG-58/ U is a specific type of coaxial cable, often used for Thin Ethernet ( 10base2) and low-power signal connections. The cable has an impedance of either 50 or 52 ohms. ...more on Wikipedia about "RG-58"
RG-59/ U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has an impedance of 75 ohms. ...more on Wikipedia about "RG-59"

A ribbon cable is a cable with many conducting wires running parallel to each other on the same flat plane. As a result, the cable is wide and flat, rather than round like more "traditional" cables. Its name comes from the resemblance of the cable to a piece of ribbon (which is likewise wide and flat). Generally the cable is marked only with a red stripe down one side though rainbow colored cables have also been made which make life easier if only one end is going to be terminated with an IDC connector. ...more on Wikipedia about "Ribbon cable"
RJ-11 (or RJ11) is a physical interface often used for terminating telephone wires. RJ stands for registered jack, which is part of the United States Code of Federal Regulations. It has six positions with two pins (electrical connections) installed at positions 3 and 4. RJ-14 (or RJ14) indicates that there is a second pair for an additional line on pins 2 and 5. RJ-12 (RJ12) or RJ-25 (RJ25) indicate that there is a third pair on pins 1 and 6. The connectors are commonly (but unofficially) designated as 6P2C, 6P4C, and 6P6C (where 'P' stands for 'positions' and 'C' stands for 'conductors'), respectively. ...more on Wikipedia about "RJ-11"
Shielded Twisted Pair, sometimes abbreviated STP, is a kind of copper wiring where a pair of wires are twisted around each other and covered in an insulating tube. The covering is designed to protect the wire from electromagnetic interference and serves as a ground. This extra protection, however, limits the wire's flexibility. The cable is commonly used in ethernet networks. The extra protection means that STP is more expensive than other cable types. ...more on Wikipedia about "Shielded Twisted Pair"
A snake cable is an electrical signal cable with multiple insulated wires or even other cables within it. They are often used in sound reinforcement, as they are far simpler to work with, and also far less likely to cause tripping and other en tanglements. Each cable within the snake is independent of the others, having its own insulation and shielding. ...more on Wikipedia about "Snake cable"

(TIA-568A/B) EIA/TIA-568A and EIA/TIA-568B are closely related joint Electronic Industries Alliance (EIA), Telecommunications Industry Association (TIA), and International Telecommunications Union (ITU) standards for twisted pair wiring. They define the pinout, or order of connections, for wires in RJ-45 8-pin modular connector plugs and jacks used with Category 3, Category 5 and Category 6 4-pair cables. ...more on Wikipedia about "TIA-568A/B"
