      Attenuation

      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

    • MTRJ Connectors

      MTRJ Connectors

      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

    • RG-58

      RG-58

      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

    • Ethernet at the Physical Layer

      Ethernet at the Physical Layer

      Ethernet is the most popular Local Area Network architecture that was jointly developed by Digital Equipment Corporation, Intel Corporation and Xerox Corporation. It consists of certain specifications and standards as well as hardware devices and components. Ethernet provides services corresponding to physical layer and data link layer of the OSI reference model. Each Ethernet physical

      DWDM (Dense Wavelength Division Multiplexing)

      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

      What is a Rollover Cable?

      A rollover cable is a network cable that connects a computer terminal to a network router’s console port. It is also referred to as a Cisco console cable and is normally flat and light blue so as to distinguish it from other network cable types. The pin-outs on one end of the cable are reversed

      Plenum Cable

      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

      Ethernet Fiber Media Converter

      An Ethernet fiber media converter is a device that allows a connection to be made between an Ethernet and a fiber optic cable. This type of connection is important in situations where both cable types are used in a single household or office. Because telephone companies often use fiber optic cables to deliver telephone and

      RG-6

      RG-6 cable is one of the more common types of coaxial cables used for commercial and household purposes. The term RG-6 is a generic label that can be used to describe a whole range of cable designs. In fact, all cable designs described under RG-6 may well differ from one another in center conductor composition,
