      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

      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

      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

    • 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

      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

      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
