    • Plenum Cable

      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

    • Cat 6

      Cat 6

      Cat 6 (Category 6) is a cable standard used mainly for Ethernet computer networking, security systems, and telephone services. Cat 6 cable is backward compatible with the Cat 5, Cat 5E, and Cat 3 cable standards. Category 6 cable is capable of transmitting voice and data up to 155 Mbps (mega bits per second), with

    • RJ-11

      RJ-11

      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-

    • Fiber Optics

      Fiber Optics

      Fiber optic technology makes use of light to carry digital signals via optical cables. Fiber optic cables are very thin glass wires made from extremely pure optical glass. This technology is based on the concept of light reflection. In the case of fiber optics technology, light carrying digital signals is reflected inside the optical cable

    • RG-11

      RG-11

      Coaxial cables are necessary for rooftop antennas and dish antennas in order to provide crystal-clear sound and audio input. RG-11 bands typically have 75-ohm wires made of copper. Polyethylene dielectric makes sure that there is minimal loss of picture and sound while the antenna receives audio or video feeds. Most users of the RG-11 have

    • RG-59

      RG-59

      The RG-59 cable is a type of coaxial cable that is used to generate low-power video connections. The cable works on two conductors that are based on a single common axis. It is also used for RF signal connections. The RG-59 cable conducts video and radio frequencies at an impedance of around 75 ohms. The

      How to Splice a Coaxial Cable

      A coaxial cable can be spliced with a minimal set of tools, but some of them are specialized. They can be found at a local hardware store. Purchase the following: Two F connectors A barrel connector A pair of diagonal pliers A coaxial cable stripper (preferably) or a knife. A knife is not recommended. A

    • Cat 5

      Cat 5

      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

    • Network Cable is Unplugged

      Network Cable is Unplugged

      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

    • Attenuation

      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
