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 optic patch panel, also known as the fiber distribution panel, is used mainly in fiber optic cable management. It helps network technicians in minimizing the clutter of wires when setting up fiber optic cables. It terminates the fiber optic cable while providing access to the cable’s individual fibers for cross connection. They are also …
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 …
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 …
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 …
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 …
Cat 3, short for Category 3, is a UTP (Unshielded Twisted Pair) cable designed to carry voice and data up to 10 Mbps (mega bits per second), with possible transmission frequencies up to 16 MHz. Cat 3 cable is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance (EIA) …
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 …
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 …
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 …
