568B, or more formally EIA/TIA 568B, is one of the International standards which include the definition for how the pins or wires in a RJ-45 cable are arranged or terminated. The termination of the cable can occur at several locations which include an individual cable connecting a computer to an Ethernet port, the ending socket …
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 …
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 …
The plenum is hidden space within a building which is used for HVAC (Heating, Ventilation, and Air Conditioning) and to run cables. Plenum space is normally above a suspended ceiling or under a raised floor. Buildings without plenum spaces will have cabling and HVAC ducts within plain view. The plenum space is normally used to …
When an error message saying, “Network cable is unplugged” is displayed, it generally means that the computer can detect that there is an ASDL and/or Cable Connection pre-configured on the computer, but an Ethernet cable and/or a cable that is supposed to be plugged into the modem is unplugged. In the case that all of …
DWDM stands for Dense Wavelength Division Multiplexing. DWDM is a technology used to increase the capacity of fiber optics that results in faster transfers of data. What are fiber optics? Fiber optics are very thin and small fibers that are used to transmit data and light throughout a computer and network. How does DWDM affect …
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 …
In the past, two main termination specifications were used. One was for UTP data cable infrastructure and the other for phone cable infrastructure. Today, structured cable systems are in use. 568A is one such standard. 568A is a standard for the pin arrangements of RJ-45 connectors on Unshielded Twisted Pair (UTP) wire. The cryptic number …
An MTRJ connector is a type of fiber optic cable that has an endpoint similar to the RJ-45 connector endpoint found in Ethernet connections. MTRJ connectors are designed to snap into the Ethernet port of a computer, modem, or wireless router and provide that computer or network with extremely fast data transfer rates. MTRJ connectors …
Attenuation is a reduction in signal strength over distance. Attenuation is a common problem of telecommunication cables that causes a decrease in data speeds on longer cables. Attenuation is also known as “loss” and can be countered by data repeaters and amplifiers. While attenuation is a problem for long cables, short cables do not usually …
