RG-58 is a coaxial cable that is used for wiring purposes. A coaxial cable, in general, consists of an inner conductor that is surrounded by a spacer. The coaxial cable is electrically charged and sometimes consists of different uninsulated conductors that remain entangled with one another. The insulating spacer of the cable is further surrounded …
Coaxial cable, also called coax, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection from electromagnetic interference, allowing signals with low power to be transmitted over longer distances. Coaxial cable is comprised of an inner core, insulator, shield, and outer cover. It is called coaxial because these sections …
The system that helps connect a computer to an Ethernet network is called an Ethernet card. Another name for such a card is Network Interface Card (NIC). It can be inserted into one of the slots provided on the motherboard of the computer. Each of these cards has a unique identification number, known as the …
RJ-11 is the standard connector utilized on 2-pair (4-wire) telephone wiring. RJ stands for “Registered Jack”- a physical connector interface most often used for telephone wire terminals. Though the RJ-11 connector has a total of 6 connector positions, typically either only 2 or 4 are actually utilized. RJ-11 connector wiring comes in two standard varieties- …
Cat 5, short for Category 5, is the current accepted industry standard for network and telephone wiring. Cat 5 is an unshielded twisted pair type cable exclusively designed for high signal integrity. The cable consists of four pairs of 24-guage twisted copper pairs terminating in an RJ-45 jack. If a wire is certified as Category …
An Ethernet crossover cable can be used to directly connect two network devices through Ethernet. These can either be single computers or they can be networks. Ethernet crossover cables are commonly used for temporarily networking two devices in the absence of a network router, switch, or hub. The principle is the same, but the connection …
Wavelength Division Multiplexing (WDM) is a technology found in fiber optic communications. WDM uses a single fiber to transmit multiple optical signals. It does this by breaking up the signal into different frequencies or wavelengths of color. The various wavelengths indicate that different amounts of data are being transmitted simultaneously. This results in an increase …
Everyday, data transfer rates are getting faster and faster as technology gets better and demands get higher. To keep up with these faster data transfer needs, fiber optic Internet access has been introduced to the public. Fiber optic Internet uses pulses of light to create an electromagnetic carrier wave that can be used to …
A printed circuit board (PCB) is a thin board "printed" with electrical wires and made from fiber glass or similar material. PCBs are commonly used in computer devices such as motherboards, network interface cards, and RAM chips. They are relatively cheap and quite fast. When the PCB is fabricated with several layers placed over one …
Multi-mode fiber is a type of fiber optic cable which is thick enough for light to follow several paths through the code. Multi-mode fiber is best suited for use in short lengths, such as those used in Local Area Networks (LANs) and Storage Area Networks (SANs). Multi-mode fiber comes in two standard widths, 62.5 micron …
